I just bought operation flashpoint gold w/red hammer and Prima guide, but when I install it on any of my computers it won't get past the logo pop-up. It just quits and gives me a illegal operation error. I have also downloaded the first single player demo which runs fine on all my computers. I have installed all the patches in the sequentialy correct order. I have tryed installing the game on 3 different OS's (win95 b, win98 se, and win2k professional) and I get the same error.
