Loading External Swf error

programming flash
1

Basically I’m trying to load a swf into another swf.
This is the code I’m using:


function startLoad()
{
var mLoader:Loader = new Loader();
var mRequest:URLRequest = new URLRequest("http://henshouse.com/Adrenaline.swf");
mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
mLoader.load(mRequest);
}

function onCompleteHandler(loadEvent:Event)
{
        addChild(loadEvent.currentTarget.content);
}
function onProgressHandler(mProgress:ProgressEvent)
{
var percent:Number = mProgress.bytesLoaded/mProgress.bytesTotal;
percentText.text = String(Math.floor(percent*100));
trace(Math.floor(percent*100));
}
startLoad();

It loads the swf properly, but at some point in the loaded swf, some functions are called, and a ton of errors are thrown at me.

*** Security Sandbox Violation ***

I honestly have no idea what this error means and how to fix it. Thanks if you can help.
