Licensing issue - license does not migrate

Now this thread would not be here if PD13 didn't tell me I am on the activation limit.
So, yes, I reinstalled macOS with a wipe, and I now have an issue with my license as I can't access the old system anymore and I can't migrate the license!
So what do I do now?
License info: Standard build of Parallels Desktop 13

 

We have reset your key. Try to use it again and let us know the results.

 

Thanks! It now alerted me of migrating the license.
