I was having the same problem. I, too, was using Internet Explorer with XP Pro
Service Pack 2. However, I followed Timelord3's suggestion and downloaded the
Full Version Netscape 8 browser (
http://www.netscape.com). When I opened and
installed the browser, it did automatically prompt for plug-ins. It showed
Macromedia Flash Player as a needed plug-in to be updated. It went through the
process and stated that the update was complete. However, when I went to a site
that uses FlashPlayer 8, it still wasn't working. So, I closed Netscape and
opened IE and it only worked after I disabled all pop up blocker or ad blocking
commands.
Also, I thought FlashPlayer 8 was not downloading from the Macromedia website;
however, if you look in your Macromed folder, you will probably find the icon.
It did download, but did not automatically install it. Howver, if you click on
the GetFlash icon, it will ask you if you want to install it. To get to the
GetFlash icon's folder...Start>My Computer>C:Hard
Drive>WINNT>system32>Macromed>Flash>GetFlash (double click on this icon) Hope
this helps...
