elicence already registered by someone else


Years ago I got cubase le 4 on this computer/soft key elicence, created an account with a email address which has been deleted!

I upgraded to le 6 on another computer/soft key elicence … Jointly owned by my ex gf and I, which is no un-useable.

I now am back on THIS computer with its registered soft key licence.

I just bought the le6 upgrade to le 7 but its saying that this soft key license is already registered to another person, which is my old email address which has been deleted… no idea how i can retrieve my log in details

What can I do?
