cannot return list of emails with listpopswithdisk

[gruant2000]

For some reason, I simply cannot get a return list of email addresses. I can get a new email to create and I veriified it in cPanel, but I am getting an empty record back when trying to list my emails.
I am on hostmonster if that helps, and i changed the port to 2083 in xmlapi.php.

Can anyone spot where I am messing up?

<?php
include("xmlapi.php");
$ip = 'my site ip';
$account = 'username';
$domain = 'mysite.com';
$passwd = 'my password';

$xmlapi = new xmlapi($ip);
$xmlapi->password_auth($account, $passwd);

$addpop_args = array(
  'domain'=>$domain,
  'email'=>'bobbyjryyy',
  'password'=>'abcd1234MN',
  'quota'=> 50);

print $xmlapi->api2_query($account, "Email", "addpop", $addpop_args);
$mylist = $xmlapi->api2_query($account, "Email", "listpopswithdisk", array('domain'=>$domain) );
require_once "xmltoarray.php"; 
$xmlObj    = new XmlToArray($mylist); 
$arrayData = $xmlObj->createArray(); 
echo "<pre>"; 
print_r($arrayData); 
echo "</pre>"; 
?>

SOLVED ...
I simply forgot to set my output type
