Embeding font issue (beginner)

Hi,
I’m having a problem with embedding of fonts. Tried several ways to do this; with the library, and with the [embed]-code.

This is my actionscript now:


//rssReader.as
package classes.RSS {
	
	import flash.display.*;
  	import flash.events.*;
  	import flash.net.*;
  	import flash.utils.*;
	import flash.text.*;
	import Main;
	
	public class rssReader extends Sprite {
		
		
		[Embed(source='/classes/fonts/Chalkboard.ttf', fontName="Chalkboard", mimeType="application/x-font-truetype")]

		public function rssReader(_xmlURL) { 
			var xmlLoader:URLLoader = new URLLoader(); 
			var xmlData:XML = new XML(); 
			xmlLoader.addEventListener(Event.COMPLETE, LoadXML); 
			xmlLoader.load(new URLRequest(_xmlURL)); 
			  
			function LoadXML(e:Event):void { 
				xmlData = new XML(e.target.data); 
				textBox(xmlData);
			}
			

			function textBox(rssInput:XML) { 
				var formatTittel:TextFormat = new TextFormat();
				formatTittel.font		= "Chalkboard";
				formatTittel.color		= 0xFF0000;
				formatTittel.size		= 13;
				
				
				var Tittel:TextField = new TextField();
				Tittel.embedFonts			= true;
				Tittel.text 				= "Test Arial";
				Tittel.defaultTextFormat	= formatTittel;
				Tittel.width 				= 130;
				Tittel.height 				= 205;
				Tittel.x 					= 10;
				Tittel.y 					= 85;
				addChild(Tittel);

With this code, the text isn’t shown.
If I remove the “Tittel.embedFonts = true;” statement the text is shown, but in the wrong font.
The file chalboard.ttf is placed in one of the subfolders (the root folder is where Main.as and the .fla-file is).

Does anyone know why it wont work?
