I noticed, that my Cornucopia account is now locked too:

Your Cornucopia3D account is currently locked because the Vue serial you entered during registration was already used by another user. Please contact support@cornucopia3d.com with "redemption" as subject, to fix this situation. Please indicate in the email how and when you purchased Vue.

Will this EVER get any better? Everytime when there is an update or upgrade, it's getting worse. And I have the maintenance plan, which does not prevent me from this procedure.
