I realize that I left out one very important element of my problem when I wrote the post. The Kindle won't let me do anything! Not only can I not go to the store, I can't read anything I've already downloaded, it won't go to sleep, it's basically useless. It must be defective, 'cause I didn't do anything that wasn't part of their directions. Arrgh.
Amazon is about to meet one unhappy techno-dweeb!!
