DayZ mod CD Key in use ?!?!

Thx for useing russian trade system

Dont play on private servers.
Or simply dont use hacks or cheats.

I guess you played on some "bad" servers. And one of them stole yout game key. But it's not 100% true.

Isn't DayZ Mod free?

Sounds to me like you might have had a cracked version of ArmA installed prior to buying the bundle, if that is true you should try a clean uninstall and registry clean. If not google is your friend in fixingthe issue, there were various issues with patching that told you your CD key was invalid, even though you never enter any and you could still play the game.

You need to send a support ticket to Bohemia Interactive Studio for that.

Maybe you've got key stealer when tryed to download a hack?

It was a bug in the battle eye thing. I can play now just fine.... And no i never used any hacks. -_- why everyone assumes that it's your own fault when something like this happens?
