Calibre won't sync with my Nook STR

I'm using .9.40 on Windows XP although I noticed the issue awhile ago it's just finally gotten to the point I'm really annoyed by it. When I plug in my Nook my computer recognizes it with no problem. I can easily manipulate the files through windows explorer. I open up Calibre and it spends a solid 40 minutes getting the list of books on device only to pop an error as soon as it hits 100%. It gives me the following message:



What gets me is it says there's an error communicating with the device and won't show the list of books but Calibre still shows that the device is connected as well as Memory Card A and has absolutely no issues with sending books to either of them.

Does anyone know why it's doing this? And if not is there a way to get Calibre to recognize that a device is connected but *not* search for the list of books? Having to wait 40 minutes every time I connect my Nook to be able to do anything with it is really really annoying and a monumental waste of time since it doesn't even get me the list of books.

Edit: I went to Preferences: Miscellaneous: Debug Device Detection and it gives me this message:
calibre, version 0.9.40
ERROR: Device already detected: A device (The Nook) is already detected by calibre. If you wish to debug the detection of another device, first disconnect this device.
