Preloader Help!

For some odd reason, after modifying the pictures for my "loading squares" preloader movie, it fails to work in any of my movies!

I have the properties enabled for all of the pictures and the script is written correctly! It works fine in the preview, but when my Flash movie is exported, the preloader is never shown.

If anyone has any helpful tips for me, please let me know!!!
This is REALLY bothering me!

Thanks!

Impossible to say without see the source code or something more informative than "it doesn't work".....

If I had to guess it's a background color thing.
