guarda che le action script per caricare un swf di FlashPaper sono ben precise e le trovi sul sito della macromedia
codice:
mask._visible=0
function carica(nomefile){
	trace(nomefile)
	function loadFlashPaper(path_s,dest_mc,width_i,height_i,loaded_o){
	/*
	path_s, // path of SWF to load
	dest_mc, // MC which we should replace with the SWF
	width_i, // new size of the dest MC
	height_i, // new size of the dest MC
	loaded_o) // optional: object to be notified that loading is complete
	*/
	var intervalID = 0;
	var loadFunc = function(){
		dest_mc._visible = false;
		var fp = dest_mc.getIFlashPaper();
		if (!fp){return;}
		if (fp.setSize(width_i, height_i) == false){return;}
		
		dest_mc.setMask(MASK)
		dest_mc._visible = true;
		clearInterval(intervalID);
		loaded_o.onLoaded(fp);
	}
	intervalID = setInterval(loadFunc, 100);
	dest_mc.loadMovie(path_s);
	
}

//Il seguente codice mostra come utilizzare la funzione loadFlashPaper() dopo avere incorporato
//un file FlashPaper SWF:
function onLoaded(fp){
	fp.setCurrentPage(50);
	// change magnification to 33%
	fp.setCurrentZoom(133);
}
_level0.createEmptyMovieClip(nomefile,102)

_level0[nomefile]._y=0


loadFlashPaper("documento.swf", _level0[nomefile] , 300, 390,this);
