Jquery/Java script is not working

Hi

I been working on my site for a while now, and then suddenly deleted it by mistake from the vps, as I thought I was deleting another site at the time unfortunately it wasn't. I didn't have a back up and now when I installed the theme again the jquery/javascript in the site isn't working for some reason anymore. for example top panel isn't dropping down, javascript slider photos aren't showing and even the arrows pointing left and right are not showing.

could some one please help if possible
