Yeah. Just yesterday, I bought a handful of books from Amazon after a long hiatus and the process repeatedly failed for some of them. I had to manually delete most of the files in my Kindle Content folder before it worked.

I don't buy that much from Amazon these days. While I do have two old registered eink Kindles, I can never be bothered to connect them to my PC. So I've been using Sats' method recently, although it's pretty convoluted.
