I lost my license. Plz help me.

I purchased a life-time license and used it well.
However, the clean installation of Mac os x hindered the use of the application.
I looked up the mailbox, but I couldn't find the mail with the license.

The account that purchased the license was leomes3010@gmail.com

andreas@folivora.ai I have sent two inquiry emails to this account

I haven't received a reply. I ask for your help.

Best regards,
