Lost info?

They say they can’t locate the email I registered, cuz I checked the privacy policy? Don’t remember I did, and if so… what can be done now?
Again I have all prove of buying (box\reg\dungle) payment details, I have all.

I need to give my partner the cubase cuz we split!
And we stuck now. Please need help so my partner will have the cubase under his name (legit owner) and then he will upgrade when he want.

Please need a support cuz we really stuck in this split issue.
Thanks in advanced :pray:
