I just bought an ebook through B&N nook. When I looked in my library and touched it, I didn’t get the option of reading it. Instead there was a button saying ‘Buy $9.99.’ I touched it and confirmed. Then it said that I can’t buy it because I already bought it. It told me to check my library in which I am already browsing. What should I do? Can someone help me in solving problem of my ebook? I would really appreciate it. Thanks.
