I have a Samsung V2.2 which is not letting me get into the "I reader" screen. When I touch the icon, a black screen comes up with nothing. Is there anyway I can download the operating system or something to refresh? It orginally worked when I purchased the thing three days ago, but now I cannot get into the screen at all. I also could not load e books successfully so right from the start this section of the tablet has not really worked. Any ideas would be appreciated.
