i have done some stupid thing - i have worked with calibre 5 library from linux (a second OS) and now i can't delete books in calibre 3 in windows 7 (my main OS).


so the question is:

is it possible to recover calibre 3 db, when it had been opened in calibre 5?

restore database doesn't work
import-export doesn't work
Calibre 5 has changed the database format and it's no longer compatible with Calibre 3. You'll need to install Calibre 4.23 which is the only version pre-5 that is compatible with the Calibre 5 database.
