When I down load a book, it gets stuck half way or 75% of the way through the process. The blue bar never goes away. I have read all about this problem but still can't get it to go away. I have the most recent verison of itunes and ibooks and have already tried to uninstall ibooks and then reinstall it, but to no avail. I have deleted the book and then redownloaded it, but nothing has worked. Would it help to know the book is from Games Workshop, 40K Chaos Codex? Any suggestions?
