VideoEvent.COMPLETE is not working in cs5.5

hi, i have a proyect wich compiles flawlessly in cs5, i decided to ported to cs5.5 because air3 does not get installed in cs5. when i try to compile i get an error…

1119: Access of possibly undefined property COMPLETE through a reference with static type Class.

any idea or workaround about this error…is not my project, i did a try in an empty project and a flv component and got the same…thanks for any help

here is my test code in case it can help:

import fl.video.*;
import fl.video.FLVPlayback;


var mivaina:FLVPlayback = new FLVPlayback;
mivaina.source = "vidInicio.f4v";
addChild(mivaina);


mivaina.addEventListener(VideoEvent.COMPLETE , loopPlay);


function loopPlay(VideoEvent): void{
	trace("aqui, aqui");
}
