This IMHO is the crappiest, most obscure error you can get while using Flash CS4 and ActionScript 3.0
If you get this error and spend hours searching for an answer, its not really out there on Google, StackOverflow, etc…
My word of advice:
- Save a copy of your project, close your original and work with the copy.
- Start deleting Movie Clips & Buttons one at a time and then compile until you no longer receive the error.
That was the only freaking way I found an fix for this issue.
Hope this helps!
