Flash not rendering in stable web site

My client has a site at Menco which was working and has not been touched in several years (I am not the original developer). It has suddenly stopped working across multiple browsers and operating systems. I've personally tested on Safari, Firefox, and Chrome with the same results on different computers.

Perhaps there is an issue with the version, but I haven't been able so far to locate anything dealing with this as a potential issue.

The code below is an example of one of the pages that results in showing the "FAIL" message:

<div>

            <!--Valid flash version 8.0-->

            <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,24" width="980" height="356">

              <param name="movie" value="flash/header_v8.swf?button=1">

              <param name="quality" value="high">

              <param name="menu" value="false">

              <param name="wmode" value="transparent">

              <!--[if !IE]> <-->

              <object data="flash/header_v8.swf?button=1" width="980" height="356" type="application/x-shockwave-flash">

                <param name="quality" value="high">

                <param name="menu" value="false">

                <param name="pluginurl" value="http://www.macromedia.com/go/getflashplayer">

                <param name="wmode" value="transparent">

                FAIL (the browser should render some flash content, not this).

              </object>

              <!----> <!--[endif]---->

            </object>

          </div>
