I've had a problem with the Kindle tool for months now. It used to work, and then it stopped. And I do have the automatic update unchecked. Hopefully the new version will fix my problem. Otherwise I'll have to keep doing what I've had to do a lot of lately - buy a book as epub and format it for my Kindle, instead of just getting it from Amazon. A bit of a runaround for me, and loss of revenue for them, but hey.
