Dinamic text and CSS with loadMovies

Here is the problem:
I have a very complicated presentation which loads movies inside movies, inside movies.
All text is loaded from variables outside flash with CSS. It all works in the single movies when they are exported, but these movies are all loaded into another movie which is loaded in the root movie. And when I export the main root movie and they are loaded the text doesn’t show. It is not a problem of target path cause I tried deleting all variables and just write directly in the text field and the text still does not appear.
Has anyone had this bug? Does anyone know how I can fix this?
