I donated to the app before you made it available in the windows store and that gave me a lifetime license and once it became available in the stoe I started getting the messages about purchasing and donating and registering again.

This means you are not using your Windows Store purchase / license.
Please uninstall all versions of FileBot that you may have installed and then only install FileBot via the Windows Store. That will ensure that are running the Windows Store edition, and that you're not accidentally running the non-Store edition.
Please read How to Request Help. The sysinfo output will tell us what version / edition you're using.
