Error 1180: addframescript is usually related to the Document class.  You should first review how you reference your document class. Go to publish settings > flash tab > click on the settings button next to the ActionScript version > check to make sure the Classpath is correct.

I received this error because I had two different pathing to my Document class because I had multiple versions of the fla.  Even though the second pathing was correct it was reading the first one and getting confused.  To be safe, delete all paths and add them again.

Also, make sure your document class is extending MovieClip.  Your Document class is probably trying to access a function like stop() which is a property of the MovieClip class.

Let me know.
