Pop-up Pro

I installed pop-up pro on http://www.valleyglen.org and it will not work. I initially used the free pop-up plugin and it did not work either.

I installed it on my testing site http://valleyglen.org/temp and it works. On the testing site I also have WPMU Dev dashboard installed as well as the scribe theme.

Since, I initially installed the free version of the plugin on my live site, I'm assuming i wouldn't need the dev dashboard or WMPU theme.

So what is going wrong.

Thanks
