You need to have the latest version of "Flash" and "Shockwave" installed. Those are browser plug ins. Give it a try and see if it helps. if you have an older system try and download all the newest service packs for your operating system.
I believe you'll have to either search for the plug ins using your search engine or simply go to
Macromedia.com
I have also noticed slow load times on their new site but it will load in due time. if you have a dial-up connection this could be very frustrating.
