I installed Arma 2 and Operation Arrowhead from steam yesterday.Arma 2 singleplayer and multiplayer work fine.Operation Arrowhead single player works fine but the multiplayer doesn't work.Every time i go to the server list and pick a server with a green icon,it goes to the loading screen and starts to load, then when it finishes it takes me back to the server list screen every time.It doesn't display a code message or anything, just takes me right back to the server list.
I didn't download any mods for the game yet.I avoid the servers with mods but i can't play any regular servers either.This only happens in Operation Arrowhead multiplayer.
Does anyone know how to fix this or what is wrong ?
