My nook all of a sudden won't open any of my books. It just says "the nook cannot read this file. It may be an unsupported format."
I know for a fact that the books are perfectly fine, and i've been able to open them previously. I reset the nook hoping that would do the trick, but it didn't work. Also, when I try to format the nook or micro SD card on my laptop, it automatically disconnects them and won't let me do it. Anyone have any ideas? Many thanks.
