I'm pretty sure I have NOT forgotten an old email or phone number, but I tried the recovery process you suggested. It was rejected.  

the form asks for my UserID.  What IS that, exactly?  It also asks for my email - I had assumed my email and UserID are the same. Am I really supposed to put the same thing in both fields? Or is the UserID something different?  I don't see a UserID in my product info page, and I've never used anything but my email address to login anywhere that I can recall.

Please, can't someone just look up my account from my License Number or Product Number?
