Comment 14 for bug 807832

I think this is the problem I am having, but I am not sure. I have a newish computer and my life has gone downhill from there lol
I have windows 7 and I believe all of my stuff is updated to the current version. last week I used calibre to add some books to my kobo and it worked. Last night I plugged the kobo into the pc to charge and it said updating, and a bunch of my books disappeared and now calibre gives me an error. I really do not know what I am doing, so bear with me please.

When I try to use Calibre it says:

Error connecting to device

database disk image is malformed

Traceback (most recent call last):
  File "site-packages\calibre\gui2\device.py", line 81, in run
  File "site-packages\calibre\gui2\device.py", line 332, in _books
  File "site-packages\calibre\devices\kobo\driver.py", line 261, in books
DatabaseError: database disk image is malformed

when I do the debugging it says this:

I have no idea what I am doing but my hubby writes code, so if it gets all complicated he might have time to help eventually ;)
