Lost key for LE5

I lost my key for cubase le5 and no longer have access to the e-mail that I had back then. is there anyway to retrieve this key?

Hi and welcome to the forum,

Get in contact with your local Steinberg support to change the email address in your MySteinberg account.

Then go thru the Reactivation process to reactivate your Cubase LE5 license to the new computer.
