Topic: Impossible to load 'StageManager' error

I just changed a color in the and now when I try the movi in fash i receive this error

Impossible to load class or interface 'StageManager'.
     var sm:StageManager = StageManager.getInstance();         
I also tried to change back again the color in the but nothing seems to work and the movie clip is completely white.

Re: Impossible to load 'StageManager' error

What version of Flash? (Must be 7.02 or later)

I was having a similar problem and read that dates of the as files can make a difference. I opened and re-saved all of them and the problem went away.
