Everytime i go to join a game i get this error. I have everything downloaded for the mod, Have verified my games (by launching) and i still get a "..." are not signed by a key accepted by this server. I wiped my entire system and re-downloaded my game from AMAZON NOT STEAM and still have the same problem. Please help! I have all files in the right place and all the beta patches install and the mod installed the right way.

did you run the game before you played dayz ?

using dayZ commander will help with much of your troubles, but before you run that, be sure you installed the game exactly as described on the DayZ wiki page.
