Tween Problems - MAD here..

Here is a site I'm working on; however, there are tweening problems with the loading bar. www.hayaladam.com/hayaladam.htm
Just go into the first folder and select a file named "image.." there

Well play wit it some time, you'll see that it'll start to have problems a little time later.

Here is the code that runs when you click on a picture item

Code:

---

        if (e.item.data.name() == "item") {
                //use the @url attribute from the item´s data property to get the url
                var iurl:String = e.item.data.@url;
                this.workBar.worker.workName.text = e.item.data.@name;

                var myLoaderTween:Tween = new Tween(loaderPB.loaderPB_in, "y", Strong.easeOut, loaderPB.loaderPB_in.y, (stage.stageHeight-loaderPB.y)/2, 3, true);

               

                myLoaderTween.addEventListener(TweenEvent.MOTION_FINISH, barUp);

                function barUp(event:Event):void {
                        imageLoader.iLoader.autoLoad = false;
                        imageLoader.iLoader.source = iurl;
                        imageLoader.iLoader.scaleContent = true;
                        imageLoader.iLoader.load();
                        loaderPB.loaderPB_in.bar_pb.source=imageLoader.iLoader;
                        imageLoader.iLoader.addEventListener(Event.COMPLETE,iLoadingComplete);
                }

               
                function iLoadingComplete($event:Event):void {
                        var myLoaderTween2:Tween = new Tween(loaderPB.loaderPB_in, "y", Strong.easeIn, loaderPB.loaderPB_in.y, -60, 3, true);
                       

                       
                        var myworkNameTween:Tween = new Tween(workBar.worker, "y", Strong.easeOut, 0, -120, 0.7, true);


                        workBar.worker.closeButton.addEventListener(MouseEvent.CLICK, closeImage);
                        nonClick.visible = true;
                        imageLoader.visible = true;




                }
        }

iLoader is a UILoader Component
imageLoader is a movieclip
loaderPB.loaderPB_in.bar_pb is a ProgressBar Component, and the parents are movieclips

I guess there is a problem with my tween loops. What I want to do exactly, is to see the loading bar go up to 100% first, then see the image in my loader.

I hope someone can solve out this problem.
