[Mendozachers]

First of all, I had an Alpha account way back, I thought I namned it Mendozacheers. Couldn't log in with it today on the forums, so I had to create a new account, namned it Mendozacheers with another alpha/beta key, because the first one was redeemed with my old account.
How do I get access to my old account, is it even possible?

Second. With me new account here, I can't log in the client. Simply says "Incorrect Username or Password", but I am here, writing a thread... So I obviously Can log in =/ help?
