Flash doesn't get data from my drupal

Hi Everybody:

I pasted the code in the tutorial here to set up a service in Flash 8. It works fine when I change it for another Drupal Service. So Flash code is allright.
The problem is with my Drupal that doesn't send the data.
Is there something I'm missing.

So here is the code:

// Picking up a Drupal node with flash remoting
// Drupal must be set up with Services module enabled
import mx.remoting.Service;
import mx.remoting.PendingCall;
import mx.rpc.RelayResponder;
import mx.rpc.FaultEvent;
import mx.rpc.ResultEvent;
import mx.remoting.debug.NetDebug;
import mx.utils.Delegate;

// expose debugging info to clientside "NetConnection debugger" utility
mx.remoting.debug.NetDebug.initialize();

// create, position, and set params on three dynamic text fields: status, node-title, and node-body
var tf:TextField = this.createTextField("status", 10, 0, 0, 200, 200);
var ntitle:TextField = this.createTextField("nodetitle", 11, 0, 50, 200, 200);
var nbody:TextField = this.createTextField("nodebody", 12, 0, 100, 200, 400);
ntitle.html = true;
ntitle.multiline = true;
nbody.html = true;
nbody.multiline = true;
nbody.wordWrap = true;

// establish connection with remote service gateway in Drupal and specify service
// - /services/amfphp is AMFPHP in Services gateway
// - node is one of the two default, exposed services in Services module. The other is view.
var gatewayUrl:String = "http://rffarias.net/services/amfphp";
var node:Service = new Service(gatewayUrl, new Log(), "node", null, null);
// call service method
// - load is one of three methods on the default node service
// - pass in which node to load (hard coded "1" here for node 1)
// - optional additonal param to node.load is what fields to return (like in a view?).
// -- array of field names: node.load(1, ['title', 'body']);
// -- default is to send the entire node. This example does that.
var pc:PendingCall = node.load(1);
// set up response handler functions
pc.responder = new RelayResponder(this, "getData_Result", "getData_Fault");

// set default status text
tf.text = "no response from server yet.";

// success result handler
function getData_Result( re:ResultEvent ):Void {
// re is the object containing the response
// two properties you can count on being populated for any node are re.result.title and re.result.body
tf.text = "response:";
ntitle.htmlText = "Node Title:
" + re.result.title;
nbody.htmlText = "Node Body:
" + re.result.body;
}

// failure result handler
function getData_Fault( fe:FaultEvent ):Void {
tf.text = "error";
}

But if you change the URL above it works and doesn't return the error. Just like for instance try another site that has a Flash example:

http://heliereric.com/drupal/services/amfphp

So if you paste the above URL in the code..it works fine.
I'm I missing some configuration?

Thanks
