I downloaded the 1.20 update on my desktop computer. I restarted and opened Calibre and my books are gone. Every one of the 1650 books are gone. I do have them backed up, but this is the second time this has happened when I do a Calibre update. I hesitated this time, but went ahead since it has been a while since my last update. I am not very happy right now. What happened? Did I do something? Where are my books?
The last time I lost over 3000 books and I have been in the process of putting them back, but I am not happy.
