Jetpack Slideshow Gallery produces noscript-error

Dear Jetpack Support-Team,

I’ve got a problem, which drives me crazy.

I started to make a gallery in the new WP 3.5 Mediacentre and selected “Slideshow” for display. First time it worked out perfectly but when I wanted to add more images to the slideshow, it was not shown again. I only see the “Activate Javascript” error, although I have javascript enabled in my browser.

I didn′t install any plugins, it just stopped working and I couldn′t get it to work again.

I’ve also got no other gallery plugins running. So this could not be the error.

Here′s the link: https://www.lifechange.at/bauen-energie-messe-2013/

Please give me a hand on this.

Greetz, Hannes
