I bought Filebot through the windows store when I was running Windows 10. I'm now running Ubuntu Linux. Is there any way to transfer the licence key or will I have to buy the Universal version?

Hi i hope someone can help me, for some reason Filebot is not renaming everything inside a folder. I drag a folder to filebot renaming part, and it use to show a list of everything in that folder, now it shows nothing only the folder. Has something changed ? because i want to rename everything ...
