Help me pleSe!!!!

Please open your debug.err file in notepad, and copy/paste the contents into a post here. This will give us some technical information that can help troubleshoot your problem. The location you'll find the debug.err in varies depending on which game you're playing:

Dread Lords: My Documents\My Games\GalCiv2
Dark Avatar: My Documents\My Games\GC2DarkAvatar
Twilight of the Arnor: My Documents\My Games\GC2TwilightArnor

Older versions may store the debug directly in the location the game is installed at.

Be sure to copy the debug immediately after the error occurs; if you start the game again, the debug will be erased and recreated for the new session.

Not sure what this is all about. Kinda got my cousin who think he knows everything to work on it a little so not sure what he did. All I knows is that whenever I start the game, black screen pop up and eh. 

Go to My Documents\My Games\GC2TwilightArmor, open the file prefs.ini, and make the following changes:

Change
DisplayWidth=1024
DisplayHeight=768
ColorDepth=32
Fullscreen=1

To
DisplayWidth=1680
DisplayHeight=1050
ColorDepth=32
Fullscreen=0

Then save the file and you should be able to start the game.

Also, you do not have the latest version of the game, so while it is probably not related to this issue, you may wish to update via Impulse.

Thank you thank you thank you.
