I've had this problem too. If I try to join a server that requires BE, it loads and what-not, but then just exits out to the server list, saying; 'BattlEye failed to initialize". I've tried uninstalling and installing BE multiple times, but it doesn't seem to do anything. When I right click on the ArmA 2 icon, it gives me the option to reinstall BE. But when I click that it begins to start up ArmA 2, but then cuts to an error message that says: "This game is currently unavailable, please try again later." Anyone know what I can do to fix this?
