Da Vinci Code: Gray Screen... can't see anything.

[fridych]

I have a few games installed and they all play ok. It's weird b/c the game (Da Vinci) gives me the sound of everything I might be doing if I could just see what I'm doing. As soon as the first movies at the beginning is finished I get a gray screen wich then turns black and I can only see the pointer at times by one of the screen corners. If I swith back and forth between my desktop and the game the options of resume game, quit, etc... will show, but w/ no color or the nice design it gives you when you are trying to select anything from the different menus. I don't know what else to try...
