1) how do you set a administrative owner, when I go and push, it just says the tablet does not have one. 2) I have Amazon Kindle on here, at first all was fine, I downloaded books, they opened, NOW, when I try to open certain books, I get the post "The book could not be opened. Please remove the book from your device and then download again." I would do this if I knew HOW to remove it? There are no buttons for removing books and when i tried to throw kindle in the garbage can or uninstall it, it is unsuccessful. Why is this so? I love the thing just for the e readers, but I am having issues with that. anyone know how to resurrect this thing to work?
