Studio Theme Slides - not appearing

Hi
Studio looks like a really cool theme, however without much documentation I am having one or two problems.
Firstly the sliders - I can't seem to get them to appear. I have no active plugin-ins, and am running WP 3.2.

Here's the site:

Secondly I'd like to know the recommended dimensions for all the various items e.g headers and also how they interrelate on the page, and whether they can co-exist - otherwise it's trial and error.

Any help much appreciated.
