codeigniter teamspeak 3 api problems when loading libraries

Question

I'm trying to develop a teamspeak web application with the codeigniter web framework. Now I had one problem.

I got following error:

Fatal error: Class 'TeamSpeak3_Helper_Profiler' not found in C:\xampp\htdocs\project\teamspeak\application\libraries\ teamspeak\TeamSpeak3.php on line 550
A PHP Error was encountered

Severity: Error

Message: Class 'TeamSpeak3_Helper_Profiler' not found

Filename: teamspeak/TeamSpeak3.php

Line Number: 550

My Controller constructor:

function __construct(){
    parent::__construct();
    $this->load->database();
    $this->load->library(array('form_validation', 'teamspeak/teamspeak3'));
    $this->load->helper(array('url'));

    $this->form_validation->set_error_delimiters($this->config->item('error_start_delimiter', 'ion_auth'), $this->config->item('error_end_delimiter', 'ion_auth'));
}

I try to load the function like this:

$ts3_VirtualServer = TeamSpeak3::factory("serverquery://myquerry user:mysecretpassword@mysearveraddress:10011/?server_port=9987");
$ts3_VirtualServer->clientGetByName("My_User")->kick(TeamSpeak3::KICK_SERVER, "My kick message");
