Local Connection w/Loaded SWF

We’ve been stuck on this for the last two days, and I thought now was finally the time to seek help.

What we are trying to do is import a swf generated by PHP’s Ming that contains two variables needed to run the another file. The parent SWF file is programmed in AS3 while the child SWF is programmed in AS2 (ming does not support AS3, yet).

What we need to do is collect the two variables loaded in that child SWF into the AS3. We have tired this:

// AS2 Timeline
    var sender_lc:LocalConnection = new LocalConnection();
    sender_lc.send('mainConnection', 'methodToTest');
// AS3 Main class
public function Main():void
            var receiving_lc = new LocalConnection();
            receiving_lc.client = this;

            var _l:Loader = new Loader();
            var _r:URLRequest = new URLRequest(SERVER_URL + CRYPT_PATH);
            _l.contentLoaderInfo.addEventListener(Event.COMPLETE, sessionLoadCompleteHandler);

        public function methodToTest():void
            trace('Run successful');

For some reason, it does not work. Are we doing something wrong?
