Category shows, listings do not

I completely removed the last version of Directory and installed and updated the latest. Adding the shortcode to my home page and choosing the grid display, it shows the categories and the sub category listings but when you click a link it takes you to a blank page. Not only does it not show the listing but it doesn't show anything from the page below the header area.

I completely removed my categories from the old version and recreated a new test category and 2 test sub categories. Still doesn't work.

my home page with the directory short code:
http://houstonhomeandlandsource.com/

when you click on the main category title:
http://houstonhomeandlandsource.com/listings-category/test/

when you click on a sub category link:
http://houstonhomeandlandsource.com/listings-category/test/sub-category-2-test/

while the old version did not work very well, it did actually take you to the listing pages. Am I missing something here? The new category, sub categories and listing pages were all created after I removed the old plugin, installed the new version and ran the most recent update.
