motionalize 10 Posted August 4, 2013 Ok so basicly, I have played for a year now without any problems and stuff. But yesterday, I got this "Bad serial number" thingy, and Ive been trying to fix it since that. I did all of these; -Run steam as admin -Run ArmA2 OA as admin -Deleted OA folders from regedit and verified game cache -Same as above but with admin rights -Reinstalling whole game and deleting EVERY arma 2 and OA files and folders. -I have tried all the ways in the sticky thread. Sooooooo... Got any ideas? PC specs and info; Win7 64bit i5 3750k AMD Radeon HD 7850 8GB of ram Share this post Link to post Share on other sites
