How recent is recent? What version do you have installed? Is it the latest version 2.2? If it is not, it is highly recommended that you update to the latest version which can be downloaded from your purchase history.
The category permalinks themselves should resolve to the page set as the Directory Home Page on the Connections : Settings admin page under the General tab. This page should have the
[connections] shortcode on it.
Does that help? Let me know. Thanks!
