How to transfer registration from one e-mail to another?

I've searched the site several times and not come up with a solution to this problem. When I registered my most recent upgrade for Parallels, it defaulted the e-mail address from my Address Book. Unfortunately, it used my Work e-mail, and I did not notice it. I would like to transfer the registration to the same account where all my previous registrations were. How do I do this?

 

Really? No one at Parallels can help me with this? I'd expect someone at Parallels monitors these forums... I'm disappointed. I've been a customer for several years now. This isn't what I'd expect from Parallels.
