Accessible PDF won't read past first page

I have created a pdf document using inDesign where I used document structure and tags to create an accessible pdf. Then in Acrobat I changed the reading order and tags again so that the Read Aloud function should read the entire document correctly. I followed all steps using this tutorial http://tv.adobe.com/watch/accessibility-adobe/preparing-indesign-files-for-accessibility/ however no matter what I try the read aloud function stops after the first page. Even if I try to read another page first it won't do anything. I don't understand what I am doing wrong and can not find any help/resources. Please help me. My pdf is located at http://yourschools.ca/wp-content/uploads/2014/12/AODA-CommGuide.pdf
