You mean “you” didn’t have access to “your” old email anymore? I was wondering why you needed to take this to private messages. After you told me that “I don’t have any Steinberg products yet, so I don’t know what the Steinberg account menu is supposed to look like, let alone what to look for to delete a license.” I got a little skeptical, but still genuinely wanted to help. Now I realize you have been a forum member since 2011 and apparently are familiar with at least a few things Cubase related.

Anyway, thanks for wasting my time!
