I keep getting an error message when I try to send a book to my Kobo touch.
When I hit send to main memory I get an error communicating with device.

This is the error
(2, 'GetDiskFreeSpace', 'The system cannot find the file specified.')

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 83, in run
File "site-packages\calibre\gui2\device.py", line 478, in _upload_books

error: (2, 'GetDiskFreeSpace', 'The system cannot find the file specified.')

Can anyone tell me what is wrong. I have done a reset on my ereader and it is still doing this.
Thanks for any help
