SkillerPenguin 6 Posted August 15, 2012 Hello, I recently purchased ArmA II: Combined Operations just for the DayZ mod. However, whenever I play it, it says "ArmA II has stopped working" and shuts down almost as soon as I opened it. I'm contacted Steam Support (I bought the game on steam), looked around on forums, asked around in community groups, and looked at videos but to no avail. Then, when I think I fixed it, it says something about it having a bad serial/cd key, I don't remember the exact message. Once again, I bought the game on steam. Please help me. Thanks!
