You sir, are fucking retarded. Go watch videos or read how to install it. Obviously, you don't have your Beta patch installed correctly or completely. You do not ask for Hackers to fix a problem of installation, or any reason otherwise.
Did you read through the posts, or watch the video through? The clan they were attacking turned off the server, hopped onto another to get behind the people making the video, turned it back on, and gunned them from behind.
