Help - Groove Agent 5 - Instruments not appearing in browser

Looked in the forums and haven’t seen anything. Please direct me if this is a known problem.
Windows 11, Cubase 12, Just installed Groove Agent 5 - Moved Media Libraries to an external drive - Not sure if this caused problem or not.

The Library Manager is the utility that should be used for that. If you didn’t you can also just open (Enter or dbl-click) one of the content files in the content’s folder to re-register the files

I did use the Library Manager. I removed and reinstalled in the original location. Still not working.
