SWF Not Displayed?

Hi,

I have recnetly noticed that on a site i did the main Flash intro doesnt load/come on at work, but the flash banner does. I tried changing the publish version to flash 5 (this is wot made the banner come on) but the intro doesnt. It has a preloader, so it shouldnt be a size issue?

All other sites viewed on there work ok?

any ideas?

:q:

u need to have the latest version of the flash player.

I could see the intro.

yeah,

but at work, due to restrictions i cant download it, so in theory if published as flash 5, which i know they have, it should work?
