Lost license on BTT Remote

I recently reinstalled MacOS and forgot to backup BTT, I also can't find license on my gmail account. How can I recover the license? I wrote email to andreas@folivora.ai 10 days ago and got no response. I like using BTT but don't want to pay again just because I lost the license to it.
