Hi, I downloaded a book from the iBooks store and it appeared to download properly (similar to many other books I've downloaded before). However, the graphics are displayed as question mark images and entire chapters are displayed with the following message: This page contains the following errors: Error at lone 1 column 1: Document is empty at lone 1 column 1: Encoding error Below is a rendering of the first page up to the error. I was really looking forward to reading my book! Can anyone help? Thank you!
