[Dreading]

I'm having a similar issue as djeaton's #1. I've been using Calibre with my Fire for about a month. Until about 3 days ago, I had no trouble with the covers displaying on the Fire. If I had the cover downloaded in Calibre, it showed the cover on the Fire. If I didn't have the cover downloaded in Calibre, it showed the title and the Calibre logo on the Fire. Now, I just have blank grayed out pages on the Fire whether or not I have the cover downloaded in Calibre.

Update: I just tried removing all the books off the Fire and then reloading them. The only covers that display are books that were originally in MOBI format. The ones that I converted from EPUB and the downloaded news magazines all have the the gray-nothing cover. Also, when I click on one of these gray covers, it initially shows this weird collage of partial app icons and covers (really hard to describe) and then goes to the book.

Clarification: Covers are showing up under books, just not on the carousel.

Update 1/17: Upgraded to the newest version of Calibre and it is now fixed.
