[HoxOut]

Hi guys, i got ArmA 2 yesterday and i want to play Epoch, i downloaded Epoch mod from DayZ commender, and downloaded ArmA 2 british and arrow head and DayZ mod from steam, but when ever i try to log in to a server i just got black screen, i can see the debug monitor and i can talk to on side chat [i'm in the server (?)] but i only see black screen, and then it just gives me something like ''Soldier George was killed'' and i got a ''Disconnect'' bottum if i relog it all the same again, and its in all the servers i even try empty servers.
Plz i dont know how to fix that problem and i realy want to play this mod. i can play in all the other mods like Overwatch, Breaking poin, origins, DayZ but i cant play Epoch :(
