Rekordbox no longer loads Master Database

Hello - My Rekordbox 5.8.7 is no longer loading my master databse. Nothing has changed since my last time using Rekordox a few days ago...

I have verified the hard drive that both my music files and master databse file are on is functioning and that it is selcted in File- Preferences -  Databse Management. 

Tracks along with cue points and waveforms are not loading. Any help would be appreciated. 

Thank you
