Not sure. Just check the serial code is correct in game.

Another tip for fixing the connection issues in general is to open the console by pressing ` (above TAB, to the left of 1), and typing 'set cl_connectionattempts 30' (without ''), this will mean that your client will attempt to connect mrore than its default ammount which is 10. It worked for me :).

I'm trying to play but my problem is the internet at my school not the game. Will let you know if I can connect as soon as i can even get online long enough.
