Hi - Newbie here. I just lost all my books - not even showing up on the cloud drive. I "chatted" with Amazon and after he did what he could, he said it would have to be reset to factory settings and someone would get back with me in 3 days.

I rebooted.

Everything else works - just when I opened a book, it flashed and when I went to open Kindle App (I thought maybe if I downloaded the app from 1 market) I get the message "Application not registered. Trying to register now)
The Kindle itself is registered and the wifi and other apps work fine. Just not the books.
