flash movie stage is blank when opened

HELP!!!
When I open a flash movie it looks normal in the key frames area but there is nothing in the stage, it's just gray. I can play the movie and click on the key frames but nothing appears on the stage.

THIS IS SO FRUSTRATING!!!!
Any help would be great!

thanks

Maybe the layers are all invisible. Do you see red X's in the layer name column? If so, click them.
