RegisterClassAlias not working :(

Question

Ok something that has me pulling my hair out!!
I've got a localConnection between two swf's working fine, I can pass the allowed data types between them no problem.  However I need to send objects of a custom class through.  I thought I had a solution when I discovered registerClassAlias, however after spending ages on it I can't get it to work!
To keep it simple I've got the code in two single frame flash files, compiling the receiver first then the sender.  It works without the registerClassAlias but as soon as I add this I get a 'SecurityError: Error #2000: No active security context.'
The receiving flash file...
import flash.net.registerClassAlias;
import model.Person
import flash.net.LocalConnection
registerClassAlias("model.Person",model.Person);
var _localConnection:LocalConnection = new LocalConnection();
_localConnection.client = this;
_localConnection.connect("_connection")
function example(person:Person):void
    trace(person.toString())
The sending flash file...
import flash.net.registerClassAlias;
import flash.net.LocalConnection;
import model.Person
registerClassAlias("model.Person",Person)
var person:Person = new Person("Darron",24)
var sender:LocalConnection=new LocalConnection();
sender.send("_connection","example",person)
Any help massively appreciated!

You don't say what it is that you have tried.
Have you tried another HDMI cable, checking the cable is attached securely, have you tried it with another TV or ensured the current TV is switched to the correct input.
