I see on the listing for B&W that many people have issues with the game and the 'MX video card. I too have this problem. The game locks up rightafter the intro. I stuck a TNT2m64 and the game ran perfectly. I stuck the 'MX back in and the game would lock up after 10 minutes of play.
I've tried several drivers and playing as "Administrator" to no avail. Has anyone conquered this problem?
