I have my friends quake live key that he gave me cause hes done playing it. But I can't sign up for a new account with his key because it says its "already in use". And I can't get a hold of my friend now to get his email and password to login.

is there anyway around this since I do have a working key. Or am i stuck since he already used it with his email? I guess i'm screwed unless I get an invite?
