imonoz 1 Posted May 12, 2012 So, I bought ArmA 2 CO from steam, to play the zombie mod Zday, some friends did it too and we installed it exactly the same. Thing is, mine doesn't work. I can't play multiplayer cause it says "Bad CD Key" and I can't reinstall the Anti cheat on ArmA 2 cause it says "This game is not avaible right now". I've tried removing the Dayz files and play it on vanilla which doesn't work either "Bad CD Key" Still I got two cd keys from each game.. did steam trick me or what? Im using Windows "XP" Share this post Link to post Share on other sites
