IVI

I have absolutely tried everything! :mad: 1) Changing the Permissions to allow my account to Run as Administrator. 2) Re-installed Arma 2 & Arma 2: Operation Arrowhead. 3) Running Steam itself as Adminisrator. Nothing works at all to get rid of the "Bad Serial Number". Also when I try to Verify the integrity of both Arma 2 & Arma 2:OA It says that " 1 file(s) failed to validate and will be retrieved. I don't know where to go from here and turst me it's extremely tiresome to have to put in 4+ hours to get DayZ running! . If anyone could offer me a new solution, it would be very helpful. - IVI( Future DayZ Player)
