I just got MOHAA and it installed just fine. When I went to start it, I could hear the sound but visually I just got a blank grey screen. After a while I would get the Main Menu of the game, but it would be frozen and the sound just keeps cutting in and out. I have an AMD Athlon XP 2800+, 1024 MB PC 3200 DDR 400 SDRAM, ATI Radeon 9600 PRO 256MB Video Card, and Windows XP. I would appreciate any help at all. P.S. I have problems running several other games as well, such as Doom 3 and Call Of Duty.
