After checking the 'Click movie to open URL' checkbox you need to also provide the web page you would like to open. You also need to include the 'http://' part of the url as well.
I've had a quick look at the source and it appears to be ok but I'll take a closer look in a moment. There are several flash movies in the page, are any of them showing correctly?
One thing I forgot to ask is have you made sure that the *.swf files are matching the ones in your directory and are they in the right place?
I've had a look at the link you sent in and found that only two of the animations have a redirection on them. They also redirect back to the home site for 3DFA. The animations are titled Carmel5 and gimiks.
I would take another look at the animations and if required update the registration.
Also, I noticed that the mouse icon would flicker between the hand and the normal arrow when hovering over the gimiks animation. Do you have anything on the page which is constantly demanding focus? It could be that something on the page is demanding focus OR the animation itself has something in a mouseover event.

Actually, just checked and the Carmel5 animation is also doing the same thing with the flickering.
