My buttonMode and my .visible doesn't work anymore

Question

Hi all, i was trying to make a movie clip visible (it starts invisible), than invisible again. It gets visible, but i could't make it turn invisible again!
Same thing happened with buttonMode propertie. I applied both only for movieClips and buttons, have no idea what is happening. Maybe i should reinstall Flash??

It worked! The changes are in red: (i took logo_btn.buttonMode = true from the function inserirSWF and put it in the previous function carregarSWF)
import flash.display.Loader;
import flash.events.MouseEvent;
import flash.net.URLRequest;
import flash.events.Event;
import com.greensock.*;
back_btn.visible = false;
var carregador:Loader = new Loader();
carregador.load (new URLRequest ("invisivel.swf"));
addChild (carregador);
homem_amarelo_btn.buttonMode = homem_azul_btn.buttonMode
= homem_verde_btn.buttonMode = homem_vermelho_btn.buttonMode
= Start_btn.buttonMode = true;
Start_btn.addEventListener (MouseEvent.CLICK, slideButtons);
function slideButtons (e: MouseEvent): void {
    TweenLite.to(homem_amarelo_btn, 1, {x:290, y:444});
    TweenLite.to(homem_azul_btn, 1, {x:252, y:478});
    TweenLite.to(homem_verde_btn, 1, {x:212, y:513});
