I am using Windows7, I have tried running it with as admin, as well as set the permissions in regedit. I've heard it might be because its installed on multiple computers, but I've formatted that disc ages ago and I've never shared my key with anyone. Anyway just ask questions or try to explain what you think, if I find a fix or some explanation I will surely reply here.
Fetz you say you used to have this problem, what solved it for you? Or do you still have the same problem?<
Btw, the whole error message is like this "Bad CDKEY - Your CDKEY has been Disabled - Contact Customer Support"
its whenever I join a multiplayer game, I do not get it when hosting local area network games, and it never says its invalid..
I just dont get this, I registered my cd key with Bohemia Interactive yesterday..
