Library does not open

Hello
I succeed to open EagleFiler. I have two libraries. One opens without problem but the other ones (the most important one) does not open. When I clicked open, nothing arrives.
However, I see it in Finder.
Does anybody knows what I have to do?
Thank you
Papou

Are you opening the .eflibrary file? Please see the What information should I include when I report a problem? page.

The log showed errors like:

Target.eflibrary/Contents.db. SQLite error code:3850, ‘disk I/O error’ errno:9

which indicate that the database file was damaged. The solution is to rebuild the library.
