I have had problems with dynamic textfields in masked movieclips that are animated or where the mask is animated. Dynamic text disappears when the movieclip moves. Even when the font is embedded.
The solution I have found is to make the mask into a symbol. Just copy the frames from the mask layer into a movieclip and synchronise it with the timeline.
