Deal Plazza - jQuery with other Libaries

Hope someone can help me again with this problem.

The problem is that i cant use extensions how use jQuery too (i tink) ore other Libaries.

I tryed to install the Facebook Like Box Extension fromt these guys:

It shows the tab but did not load the content.

In the link i post above they told something about " jQuery.noConflict()." thing but i dont get it!
