Directory Plugin Installed but not appearing

I am really looking forward to using the directory plugin, I installed it just as i did with my other plugins, and i notice there are new files (if you go to : http://aquaproducts.com/listings/ or http://aquaproducts.com/listings/signup/ ) however there is nothing appearing in my left side panel for me to configure the settings. I do have a multisite network. I installed it on the network level and then tried it on a single site as well but still nothing.) I have also tested turning off some other plugins incase there was any conflict. Can you guys help?
