I have the Bible Knowledge Commentary downloaded on my Touch. When I try to access it, either when I am on wifi Or when I am working offline, I get this message: " ERROR LOADING BOOK You do not have permission to access this book." Until a few days ago, this was not a problem. Also,I can see the table of contents as if I have access, and when I select a topic, I get this same error message. It makes it impossible to use my resources. HELP!
