Is anyone else having problems with this book from iTunes? I downloaded it and everytime I would open it would freeze, crash iBooks, or generally just act wierd. I assumed something went wrong with the file during download and it was damaged. So I contacted Apple. After many, many emails with multiple departments I was able to get it deleted from my cloud and received a refund. So I just downloaded it again... Same problems!!! So fustrating! I've downloaded plenty of other books recently with no issues, so it's not an issue with my iPad. I'm not sure what the problem might be but it seems like the original file is damaged. Any one else have this problem? Any thoughts?
