Directory Theme & Plugin Upgrade Problems

Hi all: I just updated my directory theme and plugin. It seems all my customizations are not working now.

Previously I modified the single.php file to make the pages show store images and online info. E.g. http://directory.orilliabusiness.com/listing/2-4-1-pizza-of-orillia/

Now no images are showing up and none of the custom fields are showing hyperlinks.

Any ideas on what I can do to restore the way directory pages appeared?

Thanks,

Rob
