I just recieved my new nook and sideloaded quite a few books I had previously downloaded. I have had no issues with reading the epub books, but with the 3 PDF books I have checked, after about 15 or 20 pages, no text shows up on the rest of the pages. I have checked on my computer and they read fine on it. I have tried deleting them and reloading them, but still have the same problem. Any help would be greatly appreciated. And please don't say call customer service. I understand they will probably be able to help, but would like to see first if anyone else has had this problem or knows of a fix for it. Thanks!!
