In Action Script Bildergallery funktioniert nicht richtig

Gute Abend liebes Forum,

Ich habe in ein Flash Site eine Bildergallery (Template) eingebunden. Nachdem man im Menü die Bildergallery auswählt, wird Sie ziemlich prima dargestellt. Wenn man dann nun ins Hauptmenü zurückkehrt und dann nochmal die Bildergallery wählt wird:
-In 1. Linie Die Bilder der Bildergallery nicht mehr angezeigt (Nur der Schnitt)
-Sekundär wird die komplette Seite dann total langsam...

Habe schon einiges ausprobiert leider ohne erfolg...

das ist der Code der Bildergallery:
