All you need to do is confirm the Community folder location, so you can see if any reminants of the Academy Lesson addon exists after you delete it.
Just reinstall the Academy Lessons addon via Navigraph Hub after that and test it out.
Start MSFS2024 → Marketplace → My Library →
GordonNG,
Here is what I see. I do not know what I am to modify. The only files with content are the last two. Thank you again. I will try to keep quiet the rest of the day. Dr. Frank
Open the Community folder.
You will find the Academy folder in here. All we want to do is to confirm whether or not any stagnant files exist in here when you uninstall Academy.
If there are, delete them, then reinstall Academy.
