Plugin Doesn't Seem To Hide Unpaid Blogs

Hey there,

I've been using the blog directory plugin on my wordpress multisite which also has prosites and marketpress in it.

I am trying to use the blog directory plugin to show a listing of all the sites in the network, and it does, except it shows the ones that are unpaid for as well. I see there's an option to hide unpaid blogs, and I have ticked that but to no avail, it's still showing the unpaid sites. We get a lot of people singing up and testing out the system, but never actually paying in the end, so we don't want these listed.

Any ideas what could be causing it?
