imtim83 - whoops, sorry, I'm just a little phased out/tired right now
Have you tried getting the new drivers? This has happened to me before as I have mentioned... what you might want to do is get the new Voodoo drivers (if you haven't already), re-install the game... update it w/ the latest patches, and you're set to retry
If not... you should go to the FAQ/Tech Supp and look up your problem - sounds pretty common, should be there
Good luck, I'll try to find you the link right now
