This script link (from your page's source code) is linked to a script on the hard drive of some computer, probably that old computer that you say the page works on:
Code:
<script type="text/javascript" src="file:///C:/Documents%20and%20Settings/Administrator/Application%20Data/Adobe/Adobe%20GoLive/Settings7/JScripts/GlobalScripts/CSScriptLib.js"></script>
You need to replace it with a link to the script on the server. If you haven't uploaded the script to the server, you will need to do that first. There could also be other problems but, this is a major one and needs to be fixed first.
