Somehow both the original and my external backup metadata files got corrupted and I can't open Calibre from original directory or the backup.
When I try, I get the error that there is no Calibre library.
Is there a workaround to force Calibre to open a library an reindex?
The only option I can think of is to create a new library and import all the books. That's 20K of books. Then they will not be in any date order, but all one date.
Than you for any help.
