Video file not playing after WP upgrade

So on the site Fundamental.com, we used to have a video that used to play when you clicked on the play button on the top left corner of the homepage. The homepage uses the jQuery Colorbox plugin to play the Video in a lightbox window. The video file is flash file that resides on the server.

I upgraded the site to 3.5.1 and the function stopped working. The Javascript on the page used to call the function is:

<script type=”text/javascript”>
//<![CDATA[
/**/
jQuery(document).ready(function(){

jQuery(‘.flash_button’).mousedown(function() {
jQuery.fn.colorbox({
“href”:”#mycboxModal”,
“inline” : true,
width : 660,
height : 465,
title : “Unlocking Your Business Capital”
});
});
});
//]]>
</script>
