Loading Legacy Flash 8 Content in a Flex 2.0.1 App

rewriting legacy content in as3 difficult business case make. but, if can load legacy swf (flash 8 swf) can make case of doing new content in as3 , keeping old content in as2. have been attempting do, i've run big snag.

i'm having trouble using localconnection flex project communicate flash8/as2 swf.

i wanted use localconnection pass strings , forth (as described jesse warden here: controlling flash player 8 swfs in flash player 9 swfs note: link appears down, may able recover google's cache).

when use code:

loadr= new swfloader();
loadr.height = 600;
loadr.width = 800;
loadr.y = 150;
loadr.x = 0;
loadr.source = "testingconnection.swf";
loadr.addeventlistener(event.complete,loadrcompleteevent);

i'm able load legacy (flash8) swf flex application. there no domain problems here.

but attempts @ using localconnection not paying off. error message (error #2082: connect failed because object connected).

here's code as3 side of connection (from flex):

import flash.net.localconnection;

public class as3toas2com
{
private var as3sendmessage:localconnection;
private var as2receivemessage:localconnection;
public function as3toas2com():void
{
as3sendmessage = new localconnection();
as2receivemessage = new localconnection();
as2receivemessage.connect("as2toas3con");
}
public function as2message(msg:string):void
{
trace("as2message: "+ msg);
sendas3message("test");
}
public function sendas3message(msg:string):void
{
as3sendmessage.send("legacyreceivecon","as3message",[msg]);
}
}

and here's code in as2 class use in flash cs3 fla:

class flashnineconnection
{
private var as2sendmessage:localconnection;
private var as3receivemessage:localconnection;
function flashnineconnection()
{
as3receivemessage = new localconnection();
as3receivemessage.connect("legacyreceivecon");
as2sendmessage = new localconnection();
}
function as3message(msg:string)
{
trace("flash 8/as2 receiving flex/as3");
trace(msg);
}
function sendas2msgtoas3(msg:string)
{
trace("flash8/as2 sending message flex/as3");
as2sendmessage.send("as2toas3con","as2message",[msg]);
}
}

here's code flash cs3 fla:

import flashnineconnection;
var ffcon:flashnineconnection = new flashnineconnection();
var timer:number;
timer = setinterval(getvalues,10);
function getvalues()
{
if (ffcon.messages != information_txt.text)
{
history_txt.text = history_txt.text + ffcon.messages;
information_txt.text = ffcon.messages;
}
}
ffcon.sendas2msgtoas3("as2 trying talk as3 movie");
send_btn.onrelease = function()
{
ffcon.sendas2msgtoas3("info: " + input_txt.text);
}


does have tips or advice?

disclaimer: of course code above not pretty (for example no try/catch blocks, etc)- conserve space took out lots of goodness.
