[KingCruzIII 0]

ok so i downloaded arma 2 and arma 2 oa. and i downloaded six launcher and installed dayz with that. but when ever i launch the game with six launcher when ever i try to join a server i get

"files common\modules_pmc.pbo are not signed by a key accepted by this server. To play on this server remove listed files install additional accepted keys. and i am not sure if this has to do anything at the main menu it does say arma 2 beta expansion dayz and all of that but at the bottom it says verson 1.61.9... and not what i assume it should say "1.7.2.3" this is the first time iv tried to play dayz plz any help would be greatly appreciated.

[note i did search and try to find any similar problems and i could not find any.]
