problems reading ebook in Calibre

[JannyOlree]

I have been working with Calibre for a number of years now and never had a problem. Now I tried to get my backup in and when I open a book it sais:
Fault: cannot show
This book has no avalable format
OK or copy to "klembord"

this happens with lots of books in Calibre now?? I am desperate. Can anyone help me in Dutch because English is not my strong side.

Kind regards, Janny

what is post a poll??
Please help me!!!

Your Library (DB) is corrupted. Maybe you restored metadata.db from a different system (or later recovered from an error)? the file names (###) must match exactly. Note that Google drive damages the names (###)

Run Library Maintenance (it is on the Library Icon), both phases. Fix the issues found.
