IE 5.0 and Macromedia FlashPlayer

When trying to open our department website (www.doe.state.la.us), there is a Macromedia FlashPlayer animation that displays using Netscape, but not with IE 5. IE launches Install on Demand, but this never seems to get anywhere and nothing downloads. Checking the box to not urn IoD stops this from happening, but the animation still does not dispaly. I am running SP 6a on this machine.
