JQuery-Problem with page, Google Map not loading?!

JQuery-Problem with page, Google Map not loading?!

Hi,

I have a huge problem!
I am running sobiPro on my page with an module for GeoMaps (google).
The support told me, that I have a jquery problem.
This is what they wrote me: 
 
You have there JS conflicts:
ReferenceError: jQuery is not defined
http://www.neu.nada-akupunktur.de/components/com_k2/js/k2.js?v2.6.9&sitepath=/
Line 9

TypeError: this.filter(...).css(...) is undefined
http://www.neu.nada-akupunktur.de/components/com_sobipro/lib/js/jquery.js
Line 6

At your site are loaded multiple times jQuery libraries, with different versions. One loaded by some system plugin:
/plugins/system/sboost/js/jquery.min.js">

is very outdated version. Also you are loading some unknown version of bootstrap library. All these things can generate problems which can brake Google map displaying. You need to fix them.


The page is: http://neu.nada-akupunktur.de/
And the position, the map should be loaded is "SobiPro GeoMap Module" at every page in the main section.

Now I found out that, when I choose another template, it start working (i.e. beez). So I think, that the problem might be with the template. Can I change the jquery of the template?

But I dont know what to do... Somebody any idea?
I really need to get that running and don't know what the problems are and where to start. 
I am working with the newest version of Joomla, 2.5.28.

Thank you so much guys,
Emanuel
