I found that there is a problem with some wireless routers. I haven't found a fix yet but if you go to an open WiFi like at a library or at Barnes & Noble proper you will be able to download the app and get your books back. I could also do this if I took the router off my setup. I have sent in a request to B&N support to ask for what their suggested router settings are for the Android app but they have not as of yet responded. Please note this effected my tablet, PC and laptop which all work fine with the router on. I have seen a lot of people on the Android Market having this same problem.
