Slides not showing

Hello,
This plugin was working beautifully yesterday, and it took me a long time to find one to fit the bill. But today, I’m not seeing my slides. They are supposed to be under the middle widget area (thanks to sponsors) on this page: http://toughturtleithaca.springboard-creative.com/
I’ve used both the smooth slider widget, and the shortcode, and I’m seeing nothing.
Thanks and fingers crossed!
Elaine
