jquery all the sudden won't work in my environment

jquery all the sudden won't work in my environment

Here is the situation. I know very little about jquery but I am using it for some little features in a program I didn't write but am maintaining. Our network team kindly updated my desktop with a newer java and they fixed some other things while they were on my box(they don't remember the exact list). The program ran from my development box before they worked on it now after fighting with it a bit I have it mostly working again. The only things that don't work are the jquery items like expanders and dropdown fields. I created a new war file from my box and put it on the our Test server and everything works even the jquery, so I know its not the code. Its definitately my environment. What could I be missing on my box or being blocked from that would make only the jquery stuff not work? The whole program consists of javascript, jsp, ajax and jquery.
Thanks

BTW I've been fixing my system for almost 2 weeks now, so be gentle with the answers.
