1.01: [BGII/ToB] - ChDimm.cpp at line number 508 (Back to Top)

Memory allocation error. This could be running out of RAM or swap space. Check your swap file size and make sure you don't have any extraneous programs running.

1.02: [BGII/ToB] - ChDimm.cpp at line number 599 (Back to Top)

Could not open/find a specific file either on the CD or hard drive. You should reinstall.

1.03: [BGII/ToB] - ChDimm.cpp at line 805 or 834 (Back to Top)

BG2 failed to start up. Try to reinstall. Make sure that the baldur.ini file is NOT flagged read only and make sure that the [Alias] section is pointing to the correct directories of your install.
Here is a sample of what the [Alias] section should look like for a full install:

[Alias]
HD0:=D:\Games\Black Isle\BGII - SoA\
CD1:=D:\Games\Black Isle\BGII - SoA\CD1\
CD2:=D:\Games\Black Isle\BGII - SoA\CD2\
CD3:=D:\Games\Black Isle\BGII - SoA\CD3\
CD4:=D:\Games\Black Isle\BGII - SoA\CD4\

This should let you start the game.

1.04: [BGII/ToB] - ChDataTypes.cpp at line 250 (Back to Top)

General decompression error on BAM and MOS files. This is the most common error that will occur when the game is accessing bad data on your hard drive. This can occur from a faulty install of BG2 or can occur due to some oddities with your hardware. There are no easy solutions to this issue as they are hardware specific. Try clearing out your quot;cache", "temp", and "tempsave" directories. Failing that, try reinstalling.

1.05: [BGII/ToB] - chitin.cpp at line 1621 (Back to Top)

Problem with "chitin.key" file. First try re-patching the game. Failing that, try reinstalling.

1.06: [BGII/ToB] - chsound.cpp at line 3303 (Back to Top)

Possibly running out of disk space while playing sounds. Check to make sure you have enough free space on your C: drive and where BG2 is installed.

1.07: [BGII/ToB] - chvideo.cpp at line 9302 (Back to Top)

Failed to draw mouse cursor. This is most likely bad data in RAM, so restart the computer and try again.

1.08: [BGII/ToB] - ChVidmod3d.cpp at line 889 (Back to Top)

Error retrieving frame information from a BAM in 3D mode. This is most likely bad data. Try clearing out your "cache", "temp",and "tempsave" directories. Failing that, try reinstalling.

1.09: [BGII/ToB] - CtiledObject.cpp at line 244 (Back to Top)

Could not find a specific tileset. This is most likely bad data. Try clearing out your "cache", "temp", and "tempsave" directories. Failing that, try reinstalling.

1.10: [BGII/ToB] - InfGame.cpp at line number 2689 (Back to Top)

Couldn't delete temp files. Exit the game and try clearing out your "cache", "temp", and "tempsave" directories.

1.11: [BGII/ToB] - InfScreenLoad.cpp at line 1492 (Back to Top)

Corrupt portrait bitmap. Go into the directory of the save game that is giving this error and delete all the .bmp files. Load the game and then re-save.

1.12: [BGII/ToB] - InfScreenMap.cpp at line 2676 (Back to Top)

BG2 failed to draw the map mosaic. This is most likely bad data. Try clearing out your "cache", "temp", and "tempsave" directories. Failing that, try reinstalling.

1.13: [BGII/ToB] - InfScreenSave.cpp at line 1550 (Back to Top)

This issue can be fixed by deleting the .bmp (bitmap) files from your saved games (the one that's giving you trouble). It is recommended that you move all other saves other than the one your working on to a different directory. If the process works, put another save back into the directory and continue testing until you can verify all saved games.
