Hi knstrick,
Did you close the Little Reader Touch app or switch to other apps while your lessons were being downloaded? If that's the case, please try the download again, and this time please keep the LRT app active (don't close or switch to other apps), and don't put your iPad to "sleep" mode.
Just in case, you can try a combination of the other tips listed in this article:
