Help, CS5 AS2, preload swf's into a component

Can anyone help? Ive bought a page flipper component that loads individual SWF’s externally as pages…

I have a preloader that loads my main SWF, but the page flipper still takes a while to load and needs progress indication.

the page flipper component does have its own preloaders for each page, but doesn’t show before content is loaded

thanks in advance
