Troubleshooting

This article will not contain advice on how to adjust the camera, please see its own page to do so. While this page may help you solve your problem, it would be best if you also sent a bug report to Obsidian, so that the underlying problem may be addressed. Their e-mail is nwn2bugs@obsidian.net. Please see the latest patch notes, which may explain changes between versions better.

For more advice see the troubleshooting thread on the official forum.

General advice
Many peoples problems can be traced back to the following problems, and therefore it is a good idea to go through the following list before trying more specific advice:


 * Outdated drivers: Please try to update your drivers, this goes especially for video game drivers. If you are using a Nvidia card, their driver page can be found here, while ATI owners will have to go here.


 * Old Neverwinter Nights 2 folder: Following patch 1.010, Obsidian made changes to the engine which has necessitated the need to rename the Neverwinter Nights 2 folder in "My documents" in order to take advantage of these changes (including better frame-rate).

1. Go to "My documents"

2. Find the folder named "Neverwinter Nights 2"

3. Rename the folder to anything you like (anything, as long as it is not "Neverwinter Nights 2" - say "Neverwinter Nights 2 - BACKUP"

4. Now start NWN2.

5. NWN2 will create a new folder called "Neverwinter Nights 2"

6. Exit NWN2

7. Move save games, custom ui, overrides, modules, campaigns etc. etc.... from "Neverwinter Nights 2 - BACKUP" (or whatever you called it) to the new "Neverwinter Nights 2" folder.


 * Problematic files in the override folder: Despite its great convenience and ease of use, the override folder in My documents\Neverwinter Nights 2 folder was never meant to be used for modifications and module file to such a extent as it is today. Instead it was meant to be used for builders to test their creations. As a rule it is therefore a good idea to remove all files from the override folder and then try to see if the problem persists.

See this thread.

Missing feats
A file (most likely called feats.2da) in the override folder may be "shadowing" the built-in feats (after patch 1.10 and Mask of the Betrayer the range for official feats was expanded). The solution on this problem is to either change the range of the feats in the feat.2da file in the override (not recommended) or remove the file altogether and inform the creator of the feat override.

Crash on transition
1: Select only your main character (don't select the other party members)

2: Turn off the AI

3: Rename your "My Documents\Neverwinter Nights 2 folder and launch the game, which will create a new Neverwinter Nights 2 folder free of any content to see if your transitions work afterwards as, sometimes, the cause may be a corrupted file or custom content overrides causing the problem.

4: In some cases, not having enough free disk space may be the issue. Some transitions require opening a new of different module, in which case, plenty of free disk space is needed. My personal recommendation, is to have at least 15 GB of free disk space available.

5: Bring down the console (see here - though users non English keyboards might have to use right ALT (ALT GR) + "`") and type the following

DebugMode 1

rs ka_worldmap_open("Highcliff","")

This will open the worldmap, where you should be able to transition to the destination of your choice. Remember to type

DebugMode 0

in the console to hide the triggers after you have transitionend.

Diasapperaing companions
Quote: Posted 10/15/07 12:47 (GMT) by Kianne

Just a suggestion, but I think it could help to have a sticky regarding the disappearing companions bug. It seems like every day there's another 3 posts per forum regarding this issue. I don't know if people would notice a sticky any more than these numerous posts, but it definitely appears as though a lot of people are getting hit with this problem since patch 1.10.

For those that don't know, since at least patch 1.06, summoning familiars/animal companions can cause NPCs (such as Khelgar, Neeshka, etc.) to vanish completely from the party upon an area transition. They are no longer found in the dialog boxes that ask you who you want in your party, and they are basically missing from the game forever. Furthermore, this breaks cut scenes that require those characters (such as Khelgar in the Rite of Tyr).

There are two known ways to fix this problem once it occurs:

1) Revert back to a save made before the problem happened.

2) Some people have claimed that replacing the "ROS" file of the missing companion will fix the problem. I cannot personally vouch for this, but here's how it is done: On Windows, saved games are by default under My Documents\Neverwinter Nights 2\Saves\. The ROS files are named something like "ROS-khelgar.ros" depending on the companion in question. Find such a file with the name of the missing companion from a saved game where the companion is functioning normally, and copy it into the troubled save game directory (overwrite an existing file if any). Make a backup first. I do not know if this procedure has any side effects, but people on these boards have claimed it has restored their companions.

To prevent this bug from occurring, do the following:

1) Go into the Behaviors tab of all spellcasting companions (Wizards, Druids, Rangers, etc.) and turn OFF the "Use Ability" option. Do this for your main character too, if your PC is a class that has such a summon. Otherwise, as soon as you switch to a companion to give him a command or something, your PC will summon his familiar.

2) Do not summon familiars/animal companions manually.

3) If someone has summoned his familiar or animal companion, switch to the character who owns the familiar/animal, hold down the right mouse button on the familiar/animal (either its portrait or in the game world should work), and select "Unsummon" from the right-click menu. (In theory, you could play with familiars out until you need to switch areas, then unsummon them right before the transition... but I wouldn't recommend it.)

Note 1: This bug was not introduced in patch 1.10 but it was exacerbated by the patch because in 1.10 companions on AI now auto-summon familiars/animals.

128 mb video card error
A message box informs you that you need a video card with at least 128 mb - which you do.

There are several ways that have proven successful:

Go to Star > Run > dxdiag

Click the Display Tab and look for Approx. Total Memory

If it says : n/a this solution will work for you.

First method of solving this problem is to go to run and type conf, go through the wizard. Next go under tools, go through wizard, and uncheck the remote PC box. Now go back to Dxdiag and see if it shows the memory of your card now.

If this did not work I have one final solution (the one that worked for me.) Right click on my computer and select manage and go to Device Manager. Now click Display Adapters and Uninstall everything except the graphics card you are using.

Check DXDIAG once more and you memory should show up after a restart.

Another way is to increase the "Video RAM" in the BIOS to 128 MB.

If neither of this helps then:

Click Start->Run,Type Regedit to enter Registry Editor.The Find HKEY_LOCAL_MACHINE \\ SYSTEM \\ CurrentControlSet \\ Control \\ Video

In this class,you can find some sub class like {C84A0178 - 28C2- 4D98-ACC1 -486446A5E108}or others.

Don't Worry,Find Binary values named "HardwareInformation.MemorySize ", Double click it and Mod the Value to 00 00 00 08(Means 128MB Video RAM).Do it like this!

You may find some Values also named " HardwareInformation.MemorySize ", Edit them all!

Then Type DXDIAG in RUN, you can find your Video RAM changed to 128MB.

Try to run the game.

Blank Journal
Some times the Journal of one of the characters in your party is wiped. This happens when you switch characters while the journal is open (it is really overriden by the other party member's, but since most companion's journal is empty, this essentially means a wipe in most instances).

Since a character shares journal entries across savegames, it is unfortunately recover it without a backup.

The game runs slowly
One of the main resource hogs in NWN2 tends to be the shadow options, so turning the shadow detail down will most likely help. If this is not enough, there is an extensive tweak guide here, which gives a lot of options on how to tweak the game to run more smoothly.

You get the message "A required security module can not be activated. This program can not be executed.
This messag is caused by SecuRom, a copy protection software product to deter software piracy, which Atari choose to include with Neverwinter Nights 2 (which also has the side effect that there is no legitime way to avoid having the Neverwinter Nights 2 disc physically in the drive while playing). Some problems in 1.06 caused this to become a problem for legitime the above message, but might still crop up. The following solutions have been shown to help people:


 * As a general rule it is a good idea to use a registry cleaner to make sure that no old registry causes the problems. Such a free utility can be found here, though many others can be found with a quick search with your web search engine of choice.


 * Disable, and in worst case, remove, tools which simulate CD/DVD with an image (such as DeamonTools), as SecuRom consider these to be a threat, even if no CD/DVD is mounted. In worst case a few leftover registry values from the Image Mounter software may cause the error - see above bullet.


 * Official responce that has shown to help some people:

Please open the registry editor (Start->Run->regedit) and move to the HKEY_LOCAL_MACHINE \SYSTEM \MountedDevices\ area (by clicking on this folder, you will see all the entries on the right side). Look at the entries with an alpha designation (ie: \\\\DosDevices\\\\Letter_Here). You should see one of entries with letters with duplicate entries. If you delete the duplicate entry (right mouse click and choose 'Delete' from the choices), you should be able to exit RegEdit and launch your program.

If the problem persists, please delete all REG_BINARY entries in this folder (only blue ones on the right side). Reboot your computer immediately, the entries will be re-established, and the game should start.
