Hello, i just bought the game a few day ago on Steam and whenever i go in multiplayer, 1 minute later my internet crash (even skype and browser doesn't work). I tried to reinstall the whole game, the BattleEye too, patching the game, install manually the BattleEye, port forward and enable firewall, but nothing worked. My internet kept crash and coming back 2-3 minute later. I've tried playing on the original Arma 2 and everything's fine.
Thank you for helping me.
