Guys I'm not sure what's going on with your pcs, but I just clicked on the link Scott put up and the Windows media player came up and played it fine.
I have QT on my pc but have unchecked all the file associations in it except for QT. I have had to uninstall QT in the past because of issues like you guys are having.
Firefox should not be a problem, but I do not know for sure. It's definately on your end though with the QT player. It has been successfully d/l'd a couple of hundred times already.
