Slideshow not displaying anything

I have the Dynamic Gallery Pro plugin. The slideshow no longer displays any pictures, just a blank white empty box. The thumbnails display beneath. Here is the example:

I just upgraded to the latest version of WP and the latest e-commerce plugin.

Please help, thanks!
