Chaps,
I have the exact same problem, as soon as I enter the game I get massive screen corruption. Interestingly I have a similar card to Hade555, maybe this is the problem?
System Specs:
AMD Athlon XP 2200
Win2k Pro
Directx 9.0 <- Final Release Version
512MB DDR Ram
Geforce 4MX 4400 <- I know I got boned on the vid card

Detonator 30.82 Drivers
If you need any further details of my system spec I should be able to post these on sunday.
Thanks in advance for any suggestions you guys can make.
