Restoring lost account

Hello. I have kind of anusual problem. I had an account on SWTOR a long time ago. I wanted to play on it again, but unfortunately I've changed my E-Mail adres and the old one, which were connetced to SWTOR account, is lost now. How can I restore that account? Or maybe move main character from that account to my new account (which I already created, so that would be even better).

My old email is [edit: email address removed], the main character was a bounty hunter named Hever (if I remember correctly) he was about lvl 50 or something like that.
