Actionscript 3.0 :: Old Project Converting, Cannot Create Properties?

i am taking an old as1 project and converting it into as3i believe all of my publish settings are correctthere are 2 classes in my library with base class movie clipmenucallermysqlurlmenucaller and mysqlurl each have an .as file associated with them, and are exported for actionscripton the stage i have instances of of menucalleron mouse over of menucaller, menucaller adds itself a child of mysqlurl via the menucaller.as filethe problem is that sometimes this works perfectly fine,but sometimes i get errors of "cannot create property" referring to properties of mysqlurlsometimes copying and pasting all of the layers into a new project corrects this, but sometimes it does noti have an example of the problem here:in the folder there are 2 .fla files, one labeled "works" one labeled "dontwork", self-explanatory
