canehdian 0 Posted February 19, 2015 Hello everyone, So I just downloaded Arma 2, Arma 2: Operation arrowhead and Arma 2: DayZ mod.Whenever I tried to join a server I get this message saying that certain files are not signed by a key accepted by this erver.Here is a picture. I have tried deleting all listed files, checking the game integrity of arma 2, arrowhead and dayz and even re downloading them all. Can anyone please give me some help on this one?

=DiG= Zgraphz 84 Posted February 24, 2015 (edited) that just means you need to enable the expansions you are trying to play. You do that through arma 2 OA expansion tab at the main menu... If that doesn't help, list the type of server you are trying to join, type of mod your are playing, and the map.
