So i tried to reinstall the game,
redownload it from steam,
manually install battleye,
disabled firewall,antivirus
launch the game as administrator,
forwarded ports,
tried different routers,
I even went as far to format my computer with a clean installation of windows 7.
As i said i was able to play since alpha, and after the official release it does not work, i havent changed anything at my computer (hardware,drivers,software or so).
