IBooks isnt downloading a book that I pre purchased a few months ago that came out today. It is honestly driving me crazy and I have tried everything. I have minimized the application and then reopened it, I have attempted to download the sample of the book but it won't even download that, when I try to download it the normal way, by clicking download, it just tells me to go to my purchased items and click download again, and then it goes on an endless loop and never downloads. I have tried re starting the iPad. Nothing is working. Help!
