Question1: While making changes in my main library [I have multiple], I got an error that my database was corrupted. I fixed it using the calibre backup. My question is, do I need to fix my other libraries also?
Question 2: I've been using Calibre version 2.0 and haven't wanted to upgrade as in the past when auto-updating I'd run into compatibility errors. So if I did want to upgrade, which version of Calibre is the most stable after that?
Thank you in advance for any help.
