I hope I am posting this in the right section. Anyways.
When I join a Arma 2:OA server, I get into the lobby where you can be a citizen, Military people thingy, Independent, ect. So once I click what I wanna be and all that, and then I click the join, it kicks me out of the game and brings me back to the server selection thing.
I am going to add pictures in like 5mins so you can see what I mean.
