3. The download hangs when I try to download the ebook on my Ipad.
The default Ipad PDF reader does not work with password protected PDF's.
The Ipad version of Adobe Acrobat reader for the Ipad is horrible!
You must download Ibooks for free or the Goodreader PDF reader from the App store for $4.99 for your ebook to work properly on your Ipad. You can even download the ebook directly to your Ipad with Goodreader.
When you start the download on your Ipad you must select one of these two readers to use or the download will abort. Alternately, just download on you Macbook or Imac and transfer the ebook to your Ipad via the Dropbox.
