On the Restore Page, you can probably do this. E-mail me details if you can't solve it that way. I'm jimh at jriver.
Thanks Jim ... I was struggling with what kind of information I could send you, and then realized of course that all registrations and restores had been sent by email, so (lucky for me I save everything) I searched, found, and learned that the registration had been associated with the correct account -- if it hadn't I would have forwarded it to you and asked that the associated email be changed.
Thanks for your excellent support!
