I have a Kobo ereader and use Calibre, or I was using Calibre until I stupidly hit the new Calibre update.
After the 7.24 update I now get a communication error
Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 69, in run
File "site-packages\calibre\gui2\device.py", line 311, in _books
File "site-packages\calibre\devices\kobo\driver.py", line 152, in books
DatabaseError: database disk image is malformed
I have tried uninstalling the new version and putting on an old version, that didnt help the error is here to stay . So im now back to version 7.24, and use XP
I also got this error but its been replaced by the abover error or is scared of the above error and wont reshow its ugly head,
Traceback (most recent call last):

AttributeError: 'list' object has no attribute 'add_book',
I am not that computer friendly, so this is a puzzle to me

This will teach me to update
