Now i get this error message: Fatal error: Class 'PropelPropelBundlePropelBundle' not found in D:www-filesSymfonyappAppKernel.php on line 22

Line 22 looks like this:
new PropelPropelBundlePropelBundle()

And my autoload.php looks like this:
<?php

use DoctrineCommonAnnotationsAnnotationRegistry;

$loader = require __DIR__.'/../vendor/autoload.php';

// intl
if (!function_exists('intl_get_error_code')) {
    require_once __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs/functions.php';

    $loader->add('', __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs');
}

AnnotationRegistry::registerLoader(array($loader, 'loadClass'));

return $loader;
