Hi, I just dowloaded the Arma 2 demo from steam, but every time I try to play it, i just get a message htat say "Frequency out of Range". I've looked this problem up online but all the solutions i found on other websites are not working. Any suggestions? My specs are AMD Phenom 9100e Quad-Core Processor 1.8 Ghz, 4 GB RAM, and an ATI Radeon 4670
