Stack Space?

Hi - I’ve just imported a complex Illustrator file into Flash, with .ai layers to .swf frames, then basically copy & pasted the grouped objects to respective layers. However, now in trying to test the movie, I’m getting a strange error message that I’ve never seen and is making me nervous. It reads “Cannot complete operation because there is not enough stack space” – HELP!! Any idea if this is a matter of upping the amount of allocated memory or is it something much more than that?
The imported Illustrator file was 1mg. Thanks VERY much for any insight, help!
