Where did you get the books from?
How are you transferring them to the tablet?
I'm having trouble getting the books I've downloaded from my computer to my Nook tablet. I've sent to tablet but it will not move in the format where I can read it on my tablet. Extremely frustrated!!!
That sounds like you have downloaded books in a format that the Tablet cannot read (i.e such as .mobi or .azw, etc. -- not .epub). It also almost sounds as if you are using Calibre on your computer. If that is the case, you can use Calibre to convert those books to epub format, and then send the epubs to the tablet.
If you are not using Calibre, then I suggest getting it (it is free), as it is a wonderful tool and can really help out a lot with non-DRM ebooks.
