X6 Registration problem: Serial number error with online registration

While trying to register/active the latest CorelDraw Suite X6 (without success, so far), I found out that I have two (2) accounts registered with Corel, each with its own e-mail address - I am a customer of long standing.

Each account contains different applications. Since I'll soon lose one e-mail address, I would need to transfer the contents of one of them to the other account.

Unfortunately, I have  not been able to find any link where I can either merge the two accounts or move the contents from one to the other.

Can you please help me with the resolution of my problem?
