I have searched the forum, tried all the tricks, un-installed Calibre and re-installed it. It's funny that on a clean install it still remembers where the database was located with the previous install. This implies that it doesn't un-install completely.

Regardless, when I start Calibre I get this in the Show Details:

Traceback (most recent call last):
File "site-packages\calibre\gui2\main.py", line 190, in initialize_db

File "site-packages\calibre\library\sqlite.py", line 172, in get
DatabaseError: database disk image is malformed

If I try to create the database in a new location by clicking on the "No" button, I still get an error:
Traceback (most recent call last):
File "site-packages\calibre\gui2\main.py", line 177, in initialize_db_stage2

The database and library are located on a network drive. Attempts to move the database to a local drive have also failed.

Any suggestions?
