I'm getting pretty annoyed with Calibre. I'm running the latest version on mac osx. Lately it's not been working for me at all and it doesn't show the books that are on my reader (Cybook Opus). When I connect my reader, Calibre shows an outdated list that includes books I've deleted and omits new books I've put in via Adobe Digital Editions. Also, when I try to transfer books from my computer to the reader via Calibre, it doesn't seem to work.
Anyone has any suggestions?
