Maskin a button

hey u guys…
I was doing a tutorial from your site, it is the Film Grain one.

I wanted to add more masks in the button to achieve a effect like: on rollover the masked image should show through.

It does show exactly how I want when I “Enable simple buttons” while I 'm testing the movie, but when I publish my movie, its all screwed… The image and mask are all showing up.
I am sure I wasn’t clear… Please download my file and you will be able to see it.

Thank u so much…
