That happened to me too. I ended up uninstalling and re-installing my game and making a new in-game profile. I think you only need to to the profile bit, though

I get a message saying "Files "Common\air_acr.pbo" are not keys signed by a key account to play this game, please delete them to play". I have no idea what to do here. This happens on EVERY server I attempt to enter. Some help on how to get rid of these damn files so I can play Dayz again would be great. Thanks
