All of my other current games are working without a problem: Team Fortress 2, Brothers in Arms Hells Highway, Age of Conan, FarCry 2, and Sins of a Solar Empire. Â However my favorite game of course is ARMA (I've been a fan since OFP), and I'm a bit bummed because it's not working.
I have the latest Directx driver. Â I'm running 2x nvidia 8800 gtx cards in sli mode, and my CPU is overclocked from 2.4 to 3.3 with very adequate cooling hardware.
I really appreciate your replies and I’ll try your suggestions. I will update thread if it works or not.  If anyone else have any suggestions please let me know.
