Calibre Error Message

Hi. I'm trying to have Calibre read my Kindle HD. While reading the device it gets to 'Get list of books on device' 'Updating metadata cache on device' (@97% finished) and then it fails with the message: "Error communicating with device"

Details:
calibre, version 2.5.0
ERROR: Error: Error communicating with device

I've used Calibre with this device before without a problem.

Also, I can read the Kindles information from my file explorer.
