External swf transition big help needed

Hi there,

I’m in serious trouble with an external SWF loader.
Let me explain :
I’m loading different SWF’s in a choosen area of my website, I needed a transition effect between these loadings so I created a animation movieclip that needs to be added on top, played, removed (and rewinded each time for reuse).
For an unknown reason, my external swf do load BUT the transition MC either dont play or get rewinded, meaning it sometimes hides my external SWF.

Could you please tell me what’s the cleanest way to achieve this in order to avoid these problems ?

A real huge thanks !
