Trying to uninstall then reinstall Directory Plugin

I am trying to implement the directory plugin for one of my sites, GirlyGirlDirectory.com. I was having some trouble….mainly that I could not remove unused categories (just think it was a freak blip), sooo, I uninstalled the plugin manually via ftp, then checked thru cpanel to make sure no trace of the plugin remained.

I cannot understand why part of the plugin remains in my admin dashboard. It is interfering with being able to successfully add the plugin back in via fresh download. It's importing those default categories that I do not want. Also, doesn't this plugin have a default theme? Any ideas?
