Why does my .swf not load

[mandlebaum]

I ahve built a website in flash, and just put it onto the internet. On some computers the website loads perfectly fine, but on other computers, the site doesnt load at all. It shows there this a white box representing where the .swf should be playing, but it wont play it. Are there any reason, why it might not be working? Any suggestions are welcomed. heres a link to the site, if that helps at all. Its not fully loaded, just because its pointless for me to load the rest of the external .swf's if it doesnt work anyways. I just have it loaded at a site that noone attempting to view the site to see, so it will also be at a regular domain.

Thank you for your help..
