Hello
My problem is I bought a book from Amazon, like I do often. I own a NOOK 9 inch color tablet. I have converted, removed, rebought and converted again and it won't open on the NOOK. I may eat the giftcard which bought this one and rebuy it on Barnes and Noble. It is the only one I can not get to work. I do not know what I am doing wrong or right. Any one have any suggestions> And simple please. Not smart for this.

Thank you
