Exporting a PDF from QGIS Print Composer for Avenza Pdf Maps

Alright I actually did this successfully a few months back following these steps http://www.avenza.com/resources/blog/2016/12/06/exporting-qgis-avenza-maps.

Now when I bring the map into Avenza, I get a "Map Not Referenced"

Now I have no clue what I am doing wrong. I have tried and tried. I have unistalled and reinstalled. Tried to export as image then convert format.

A strange thing to note, I can not select reference map under Print Composer-> Export Settings -> Reference Map.
