Because of my ban I bought a CD-key for 5$.
I changed my CD-key through CD-key changer.
Now when I join a DayZ server it tells me ''Bad serial number given in setup''.
So I looked on some forums how I could get rid of that message.
One of them told me to run steam as an admin and open the OA again.
But when I do it automatically switches back to my old CD-key.
Anyone got a solution?
