Slideshow hangs in Browser

G'day

I've a weird problem!
Opening the Website through the Joomla-admin-panel as preview the homepage with the slideshow presents perfectly.
But if I open directly the web it hangs and shows just the loading process.

www.wildrabbit.ch

Firefox 19, IE 9
Joomla 2.5.9/Template Templaza Diary (some quickinstall demo data)
Slideshow CK incl. plugin

thanks in advance

Hi
try to delete the first slide with the video.
By my side the slideshow works but you have someJs error in your page that you should fix :
