The We site has a Redirect Loop

Hey,

I've installed directory a few times and cannot get it to work correctly. The first few times it wouldn't generate the pages mentioned in the installation instructions. Now I am getting "this website has a redirect loop" whenever I visit the listing page; http://essexhasit.com/listings .

I'm a novice so I would appreciate any detailed help that you can offer to get this plugin working smoothly.

If it matters my hosting is a shared hosting through a small orange. I would be happy to give you the admin credentials if you were willing to look at the back end.
