Can't Link to a URL from FLA

This used to work but it no longer works. Very frustrating. If I paste the URL from the code below into a browser, it works. However, if I run this as a SWF file, it doesn't work. You need to wait for the default time out and you'll eventually get an IOError 2032. A few weeks ago this worked and I have four previous projects packaged as AIR for Android and AIR for iOS and it worked. I don't know why it's stopped working.

Here's the code:

var fname = "Mac";
var lname = "Donald";
var email = "mac@farm.com";
var baseURL = "http://www.pjrules.com/litnip/";

var post = baseURL + "newlogin.php?fname="+fname+"&lname="+lname+"&email="+email;
var urlLogin:URLRequest = new URLRequest(post);

var urlLoadLogin = new URLLoader(urlLogin);

urlLoadLogin.dataFormat = URLLoaderDataFormat.VARIABLES;
urlLoadLogin.addEventListener(Event.COMPLETE, loginData);
urlLoadLogin.addEventListener(IOErrorEvent.IO_ERROR, IOErrorHandler);

function loginData(e:Event): void {

var uid = urlLoadLogin.data.result;

trace("In loginData and uid = " + uid);

}

function IOErrorHandler(e:Event): void {

trace("Error: " + e);

}

I sent a similar request two weeks ago but there's been NO response. Sure could use some big brains to help out here.

Cheers,
