Account Management?

[Mitch24]

I've bought the game like 1 week ago, i was still playing the beta since the new patch, when i try to log on the game, they want me to write the cd-key. So i take the cd key i got from GamersGate(direct Download) and when i click ok, its says, already bound to an other account. How can i know witch account it is, or manage that, I only got one GameSpy account and im logging on the same one in the Beta. How can i retrieve or manage that??

Need help
