Adding new sermon stalls on "Save"

Just installed Sermonspeaker on our site www.newroc.org . (link = All New Sermon Page)
Adding new sermons worked fine the first 2 or 3 times, but now when I add a new sermon and click "Save" the page stalls and just sits there. It actually does save the sermon, but I have to refresh the entry page and then close it out manually to add another sermon..... Any thots?

To me it Looks like you have much outdated installations of Joomla and SermonSpeaker on your site.
Joomla 1.6 was the first release of the current stable 2.5 series. You really, REALLY should update your site to Joomla 2.5.13 as soon as possible. There are multiple security issues fixed in between. There really is no excuse in not doing so.

As for you issue. Changes are it will go away if you update your site. It shouldn't have to do anything with SermonSpeaker nor the database. Those can handle much more Sermons than what you have currently.

So please update your site and then test again. If the issue is still there, I can have a closer look.
