Slideshow doesn't show up with the theme ''html5 shell by mimoYmima.com''

Hi,

I’m using the last version of Worpdress 3.5.1 with the theme ”html5 shell by mimoYmima.com”
I installed Slideshow correctly, put it on the home page, but it doesn’t show up. I’ve tried with another theme, Twentyeleven, and it works correctly.
I can actually see it the code source of the page, but it doesn’t work. I don’t have any error message.

Is it a problem of compatibility or maybe because i’ve modified the theme?

I don’t know if you need more informations, let me know

Thanks
