I'm trying to connect to my wife's Kindle Fire from Calibre.

I can see the kindle is connected but I'm getting the above message and the following description:

Cannot write to file: hr=2147500037 facility=0 error_code=16389 description: Unspecified error

Traceback (most recent call last):

Any help would be much appreciated.
