Can anyone help me ?

Answer 1

Your getAutoLoaderConfig() method is incorrect.
Try this once:
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
),
),
);
}
Pay attention to the key namespaces in the array.
In your instruction video at 4:40 they also use the plural :)

Answer 2

I solved the problem by adding a string to composer.json:
"autoload": {
"psr-0": {
"MyModule": "module/MyModule/src/"
}
}
and then, in the console, I navigated to the project folder and ran:
php composer.phar update
