Font in shared library

Question

Hello everyone
Been reading all your posts and tried everything, but nothing seems to work. The problem is:
index.swf as a class named AssetsLoader.as. This class loads sharedlib.swf which as a font in it. I need to register the font at index.swf, but i get this damn error
Error #1508: The value specified for argument font is invalid. at flash.text::Font$/registerFont()
Here are the files:
***sharedlib.swf***
Font properties at library panel:
-Export for ActionScript (CHECKED)
-Export in frame 1 (CHECKED)
-Class: DINBold
-Base Class: flash.text.font
**AssetsLoader.as***
var _loader = new Loader();
_loader.addEventListener(Event.COMPLETE, loadComplete);
_loader.load(new URLRequest('sharedlib.swf'));
private function loadComplete(e:Event):void {
var _fontClass:Class = e.target.applicationDomain.getDefinition('DINBold' ) as Class;
_index.addFont(_fontClass);
***index.swf***
var _assets:AssetsLoader = new AssetsLoader()
function addFont(_fontClass:Class){
Font.registerFont(_fontClass);
PROBLEM:
ArgumentError: Error #1508: The value specified for argument font is invalid. at flash.text::Font$/registerFont()
FOUNDED SOLUTIONS THAT DOESN'T WORK FOR ME:
#1 (at AssetsLoader.as)
var _loaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null);
_loader.load(new URLRequest('sharedlib.swf'), _loaderContext);
#2 (at AssetsLoader.as)
var _loaderContext = new LoaderContext(false, new ApplicationDomain(), null);
_loader.load(new URLRequest('sharedlib.swf'), _loaderContext);
#3 (at AssetsLoader.as)
var _loaderContext = new LoaderContext(false, new ApplicationDomain(ApplicationDomain.currentDomain) , null);
_loader.load(new URLRequest('sharedlib.swf'), _loaderContext);
#4 (at AssetsLoader.as)
var _loaderContext = new LoaderContext(false, new ApplicationDomain(ApplicationDomain.currentDomain) , null);
_loader.load(new URLRequest('sharedlib.swf'), _loaderContext);
#5 (at AssetsLoader.as)
var _loaderContext = new LoaderContext(false, new ApplicationDomain(ApplicationDomain.currentDomain) , SecurityDomain.currentDomain);
/* this solution throws an error saying
SecurityError: Error #2142: Security sandbox violation: local SWF files cannot use the LoaderContext.securityDomain property. */
The strangest thing is that e.target.applicationDomain.hasDefinition('DINBold' ) always returns true!
Been trying to solve this problem for the last week.. I really need your help!!!!!!!! I'm going crazy with this thing.....
Thank you

Noticed it's an old post but since it's been brought back...
sharedlib.fla - I used Arial for the library font in this example.
AssetsLoader.as
package  {
    import flash.events.EventDispatcher;
    import flash.display.Loader;
    import flash.events.Event;
    import flash.system.ApplicationDomain;
    import flash.net.URLRequest;
    public class AssetsLoader extends EventDispatcher {
        public var fontClass:Class;
        public function AssetsLoader() {
            init();
        private function init():void {
            var loader:Loader = new Loader();
            loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
            loader.load(new URLRequest("sharedlib.swf"));
        private function loadComplete(e:Event):void {
            fontClass = (e.target.applicationDomain as ApplicationDomain).getDefinition("Arial") as Class;
            dispatchEvent(new Event("sharedlibLoadComplete"));
Main movie
import flash.events.Event;
import flash.text.Font;
import flash.text.TextField;
import flash.text.TextFieldAutoSize;
import flash.text.TextFormat;
var assets:AssetsLoader = new AssetsLoader();
assets.addEventListener("sharedlibLoadComplete", sharedLibLoadComplete);
function sharedLibLoadComplete(e:Event):void {
    Font.registerFont(assets.fontClass);
    setTextfield();
function setTextfield():void {
    var textfield:TextField = new TextField();
    with (textfield) {
        width = 100;
        height = 10;
        autoSize = TextFieldAutoSize.LEFT;
        embedFonts = true;
        defaultTextFormat = new TextFormat("Arial", 12, 0);
        text = "A TextField using runtime shared font.";
    addChild(textfield);
