Slideshow loads but doesnt switch

Greetings.

I'm experiencing an unusual behavior of my Module in my site.

The slideshow loads normall BUT at the first slide tries to load the next but gets stucked and the slide show becomes manual instead of automatic slide show.

I was trying to update my module but my server provider has blocked the permissions and i'm unable to update anything.

My site is a Joomla 2.5.19 (unable to upgrade further due my provider's blockade)
And i can't recall the current version installed there.

The site is
Thanks in advance

Hi
there is no problem by my side with the slideshow, but you have some JS errors in your page that you should fix
you can see them in your browser console, and this can be a source of problems
