Playback Error - An error occurred loading items to play



I was listening to my Plex music and then all of the sudden it quit playing. I logged into my Plex Server (Windows 10 Pro) and tried opening from the Web app and saw the 'Playback Error - An error occurred loading items to play.'. This is happening for ALL of my movies, music, everything now. Just started happening today.
- I have run a 'repair' via Programs & Features (not fixed)
- I have uninstalled Plex and re-installed v (not fixed)
- I have upgraded to newest (not fixed)


I was able to get this fixed, unfortunately I had to run through a complete uninstall and reinstall so it is reloading all the metadata now.
