Reactivating Glasswire

I had to uninstall Glasswire completely because it had stopped working when my Windows 11 build was upgraded to version 22000.708 (it didn’t open its window any more). Now, having reinstalled the latest version, I would like to reactivate my Elite subscription. Searching my emails, I found the Cleverbridge invoice but no product key or whatever I need. Could you help me out please ?
