My ArtSlider isn't working.

I have set up a category, I have 2 articles in that category.

I copied, exactly, what is laid out on http://www.astemplates.com/joomla-template-documentation/240-164-modules-configuration for that module. The only difference is that I have 2 listed instead of 3 articles.

I just see a spinning wheel and nothing comes up.

How can I proceed from here?
