License # within program?

Is there somewhere within the software that I can find my license #? I’m excited to get to GP3

https://www.gigperformer.com/gig-performer-upgrade-request-form.html

Right, I got to that page but I don’t know my license # which is required.

Didn’t you get your license in an email when you bought or upgraded to GP2?
You can submit that form without your license, it just takes us a bit longer because we’ll have to validate you manually

I did but I’m having trouble locating it amongst my saved and deleted emails. I’ll fill out the form without it.
