[ILB]

My Calibre crashed. And now I can´t open my library - only a new, empty one.

I already tried to restore Calibre by restoring my backup from Norton - no change - and by restore the backup by calibre (as I have tried to change in Calibre to my normal library). Then I get the following message:

The library seems to be corrupted- Do you want to try a restore?
Details:
Traceback (most recent call last):

If I then try a restore:

Location database backups restored. Do not interrupt the process, this will be done in three stages. (Translation from German)

The program runs for some time and then comes the following error message:

Database recovery failed. see details:
caliber, version 0.9.38
ERROR: Failed: Database recovery failed. Click for more information "show details".

Traceback (most recent call last):

** File "site-packages \ caliber \ library \ restore.py", line 279, in replace_db
Windows Error: [Error 32] The process can not access the file because it is being used by another process

I have no idea of what other program uses this data. I had closed a all other programs and Norton Backup disabled while I have run the Calibre backup.

What can I do?
