Yea, something to do with the Voodoo card. I'm not sure but I don't think the Voodoo cards are supported very well for XP and the newer games, especially for OpenGL. There might be "homebrew" drivers which support XP, and I actually used some to get Ghost Recon to run back in November, but since I've upgraded to a Geforce 2. That would be my solution, just upgrade the video card, they are pretty cheap now.
