Guyz,
I also got problem, but mine worst then ever.

[PROBLEM]
Problem : Upon loading the game, graphic card crash, can hear sound only
Location : What location??! Cannot even play meh!
Time : Everytimeee....!!
Ping : Cant ping, graphic crash oledi man, have to restart.
Setup : AMD Athlon XP 2500 Barton with GeForce 6800XT, 512MB DDR High Performance, SIS mobo chipset(farrrk!)
Likely Source : The Game itself, lack of testing, put up false system requirement

[SOLUTION]
Problem : the above
Solution : Google for solution, test, but still not successful.
