cannot upload neither browse

Hi,
I´m looking for help to integrate CKFinder to CKEditor.

I can go to 'Images' and can see the 'Upload' Button and can see 'Browse Server'.

Both does not work:

1. Browse Server brings me to someting called 'Basket', but can´t see my images.

2. Upload stops with Error: "Ihre Anfrage konnte wegen Authorisierungseinschränkungen nicht durchgeführt werden." Means in english something like: "your request could not be handled because of authentication restrictions."

I setup the config.php as I understand:

<?php

function CheckAuthentication()
{
   return true;
}
$config['LicenseName'] = '';
$config['LicenseKey'] = '';

 error_reporting(E_ALL);
 ini_set('display_errors', 1);

$baseUrl = 'http://www.xxxxxxxxxxxxxx.de/_pics/_content/';
$baseDir = 'd:/www/www4/_pics/_content/';


$config['Thumbnails'] = Array(
      'url' => $baseUrl . '_thumbs',
      'directory' => $baseDir . '_thumbs',
      'enabled' => true,
      'directAccess' => false,
      'maxWidth' => 100,
      'maxHeight' => 100,
      'bmpSupported' => false,
      'quality' => 80);


$config['Images'] = Array(
      'maxWidth' => 1600,
      'maxHeight' => 1200,
      'quality' => 80);

$config['RoleSessionVar'] = 'CKFinder_UserRole';
//session_start();

$config['AccessControl'][] = Array(
      'role' => '*',
      'resourceType' => '*',
      'folder' => '/_pics/_content/',

      'folderView' => true,
      'folderCreate' => true,
      'folderRename' => true,
      'folderDelete' => true,

      'fileView' => true,
      'fileUpload' => true,
      'fileRename' => true,
      'fileDelete' => true);

$config['DefaultResourceTypes'] = '';
$config['ResourceType'][] = Array(
      'name' => 'Images',
      'url' => $baseUrl,
      'directory' => $baseDir,
      'maxSize' => 0,
      'allowedExtensions' => 'bmp,gif,jpeg,jpg,png',
      'deniedExtensions' => '');
