I posted this under the Fire section, but wasn't sure it would get answered there. I just got a Kindle Fire HD and was downloading some apps onto it just fine with the amazon store. After I DL'd a handful though, every app I open in the store just says "Save for Later" theres no green "Get app" button. I click save, go to my save list, and still can't DL it. I didn't DL a whole lot of apps, so I can't imagine the 16GB HD is anywhere near full. Is there a limit to how many apps it can have/download in a certain time?
