Hi I recently bought the Arma 2 complete collection, and I have ran all of the expansions and arma2 itself. I have installed the latest Beta patch, I have downloaded several Dayz mods to the latest patch of Dayz commander, yet I can't seem to join a single server. As soon as I join I just get returned to the lobby with no error message or kick/ban message. I have searched for solutions but I cant seem to find any for this problem. any help would be appreciated
