I see. I'm able to join now, thanks. I doubt I got scammed, I bought it from Steam. I've heard there was a free version of Arma 2, but it wasn't recommended so I didn't bother trying it.
Meanwhile, actual hackers must be rolling on the flor laughing at us and the admins. I'll see if I can ask for a refund, I shouldn't have bought this game. I also bought a new HDD and 4gb of RAM just to play it =/
Not sure if BattleEye sucks and is banning random players, or hackers can now ban too (we already know they can teleport everyone and kill us, like the other day).
