Forum:Problem with Call of Duty:World at War

My WaW copy doesent let me to go multiplayer NEVER.When i try to create a online profile,it wont let me,i've tried many,many unusal nicks but it wont let me.Anyone having this problems also?

Oh,and a question about hackers in WaW:

Are they harmful to my computer,or only use cheats etc.?

Thanx in advance
