I can't change my name... it says "The registration key you entered does not seem to be valid" and when i put in my regi key... it says its in use?? WTF is going on?

What did you change it to?

i WANT to change it to Craul but it won't let meh...

Well then that mean that someone else has that anme regged on another key, keep in mind that if you change your name anyone can change it to their and steal it.
