Media Pool empty but everthing is in timeline

I've been editing in DR for several years, and released smaller projects. This is my first over an hour in finished length, and doesn't use that many elements to it. Hence, I didn't use any bins, since there were only like 10-15 things and all appeared in the Master media pool.
I've been working on it for about a month, and all of a sudden yesterday, the media pool went totally blank. I don't mean 'off line' - I mean totally blank - nothing there at all! (One can't re-link if there is nothing there!) The clips appear as normal in the timeline.
The timeline is there and I can even still work on it. But this makes me extremely nervous. I had worked several hours after my last backup before this occurred, and it's a huge editing job, so I don't want to go back to the previous backup.
I have searched extensively for any hints as to how to restore the media pool, maybe from the timeline, but I am finding nothing about it. I am using DR Studio 19.1.4 Build 11. I can't figure out how to post a screen capture in here to show what I'm seeing.
Any suggestions would be greatly appreciated!
