Here is a thought.
I had a test page on my site for easy creating keys from email addresses.
That page is: http://www.fivemasted.com/testemail.aspx

Type in an email address that you would use as the registering address and hit the Get Hash send email button.
It should give you a key. You can disregard the error about not sending an email. I think that changed along the way and broke.
