AJAX Pagination Not Working

I’m trying to transition our sermon page to Sermon Manager and I haven’t been able to get page navigation to work correctly. With WP Page Navi on, the AJAX call never finds the page. It eventually reloads the first page. With it off, there’s no pagination at all.

I like the plugin and would love to use it. Are there any fixes for this issue? The URL is http://gracecrossingchurch.org/resources/sermon-audio/
