Doh! My game is still crashing to the desktop. Three or five minutes into the game now, it will crash during dialogue, battle, loading, hell whatever. No error messages. It just drops.
I tried what you guys told me. I tried to install the patch. Didn't work. I tried uninstalling and then reinstalling, then patching. Still didn't work. I tried to play via turning off my Sound Card to see if that will help. Didn't work again. I have the 3D Acceleration off too.
This started happening when I installed ToB, and since now my character is integrated into it by having the XP cap removed.. I just don't feel like uninstalling and redoing him.

Please guys. Any help would be appreciated. I just got out of the Underdark. I'm so close to finishing the game and moving to ToB, to being able to play the great expansion.. and now it's damned from me..
((Oh, btw, thanks again guys! The advice on killing Arkanis TOTALLY helped me out. Thanks again for that guys!))
