I got that problem fixed and got registered, but now I cannot log in. It keeps telling me "Can't connect to server: invalid name or server not reachable." I am sure that I have entered the right user name.
Windows Firewall is off. I have no router. I do not know how to open ports or what they are =P. It may be the fact that I am in a campus dorm which I have to connect through the college perhaps? Might just be a lost cause.
You have to register on the website, then log in with the client. If you try and register with the client you will get this problem.... at least I did.
