Well , hello there. Yesterday I installed Arma2 + addon ( By CD , no Steam version ) and tried to play. I installed the newest patch and the updater for the DayZ server but still I cant play because each server I join , shows up the message " this server is running an incorrect version of the server side application". (On some I stack on the "Waiting for player to create ..." but just on a couple ) So can anyone say me how to fix this ? And why is this even happening ? Is this a problem from the servers or from me ?!
