Only half a book

I purchased an ebook from my campus bookstore, and my only option for reading it was through digital editions. I followed all the necessary steps to install the program and download the book. However, only half of the book will load. I can only read the right hand page (i.e. every odd numbered page). All of the other ones say "chapter" at the top, and nothing else. I can highlight the whole page as if there's text there, but it's completely blank. Anyone have the same issue or know how to fix it?
