Does anyone see the green ball with this code in Flash Pro CC?

Question

If you can see the green ball at the top let me know what you did, thanks. I have Windows 8 PhotoShop CC.  I am very new when I only have the code below open in Flash saved as a ".as" when I press CTRL+ENTER nothing happens. The problem I believe is when I open another new document or ".fla" file and when it allows me to preview the screen after pressing CTRL+ENTER there should be a green ball at the top of the page, but there isn't
P.S. WHen I click F-9 to bring up the code and then CTRL+ENTER its just a blank screen with #333333 as the stage color size 640 X 480 and 30 Frame Rate

confirm using the trace function shown below.  what do you see in the output panel when testing your app?:
package{
     import flash.display.Sprite;
     import flash.events.Event;
     import Box2D.Dynamics.*;
     import Box2D.Collision.*;
     import Box2D.Collision.Shapes.*;
     import Box2D.Common.Math.*;
     public class Main extends Sprite{
          private var world:b2world;
          private var worldScale:Number=30
          public function Main(){
trace(this);
               world =new b2World(new b2Vec2(o,9.81),true);
               var bodyDef:b2BodyDef=new b2BodyDef();
               bodyDef.position.Set(320/worldScale,30/worldScale);
               var circleShape:b2CircleSHape;
               circleShape=new b2CircleShape(25/worldScale);
               var fixtureDef:b2FixtureDef = new b2FixtureDef();
               fixtureDef.shape=circleShape;
               var theBall:b2Body=world.CreateBody(bodyDef);
               theBall.CreateFixture(fixtureDef);
               var debugDraw:b2DebugDraw=new b2DebugDraw();
               var debugSprite:Sprite=new Sprite();
               addChild(debugSprite);
               debugDraw.SetSprite(debugSprite);
               debugDraw.SetDrawScale(worldScale);
               debugDraw.SetFlags(b2DebugDraw.e_shapeBit);
               debugDraw.SetFillAlpha(0.5);
               world.SetDebugDraw(debugDraw);
               addEventListener(Event.ENTER_FRAME,updateWorld);
          private function updateWorld(e:Event):void {
               world.Step(1/30,10,10);
               world.ClearForces();
               world.DrawDebugData();
