Love the eBook! Thanks Mark! The progressions and landmarks used to know when to progress are great!
My only problem: I am able to download the PDF to my PC, my iMac, and even load it into my iPod Touch (where I want to view it using either iBooks or a Readdle PDF reader application). I can read it just fine on the PC and iMac, but on the iPod it keeps crashing whatever application I use to open it. The exception is if I open it using the Safari browser or the built-in browser in the Readdle app.
Has anyone found a solution to this problem? Is this a situation where it can only be accessed directly online?
