hi,

while trying to add new books to updated calibre library, get the following message, which to me does not make a lot of sense.

Traceback (most recent call last):
File "site-packages/calibre/gui2/add.py", line 366, in add_book
File "site-packages/calibre/db/legacy.py", line 211, in create_book_entry
File "site-packages/calibre/db/cache.py", line 57, in call_func_with_lock
File "site-packages/calibre/db/cache.py", line 1471, in create_book_entry
File "site-packages/calibre/db/backend.py", line 793, in execute
File "src/cursor.c", line 231, in resetcursor
CantOpenError: CantOpenError: unable to open database file

I get this error for every book I try and add,

What am I doing wrong, what can I do to remedy, if at all possible.

Grateful for any insight anybody may have.

- Working on a Mac, with updated OS and Calibre 2.17 -,

Thx
