All of my backup files are missing
I have lightroom 3.
I've been working on editing pictures from a session daily, for the last 3 weeks or so. Every time I stop working, I close lightroom, and it automatically backs up. Because of this habit, I should have several backups to choose from, from this session, but also over this whole year. Today, when I was working, lightroom froze up for a bit, and I had to shut it down. When I tried restarting it, it said my catalog was corrupt, & asked if I wanted to fix it. I said yes, but it was still having trouble. I shut it all down and restarted my computer. When everything was up and running again, my catalog, along with all of the back-ups were missing. I've lost all of my work, and I'm feeling panicky.
Hoping somewhere out there can help?
