Well, well, after 2 months of trying to play the game, I can finally play it without crashes. The game kept crashing on the first Warfare Campaign mission. It would seem this was caused because the specs that I've read (512MB minimum, 1024 recommended) don't really apply. I've always had 1024 in this machine, but the problem was fixed when I inserted an additional 512MB. Don't get me wrong, I was able to play a bit before that, but as soon as it had a lot to load, the game just crashed. Well, at last I'm able to enjoy the game that I've paid more for than I've ever paid for any game.
