Yeah. I "bought" a Kindle copy of There Will Be War awhile back to get access to a few of the short stories in the collection.

After reading about how they're taking away downloads I went and downloaded all of my books and found that at some point they must have lost the license to that book because I no longer had access to it.

Love it when my "purchases" can be taken away from me with no recourse. edit: and I was never even informed that the book had been taken away. It just is there in my collection with a few invalid characters at the front of the title and no cover picture. The link goes to a page that doesn't exist. And searching for it shows only paper copies now by third parties. So I know this isn't just a bug in the system.
