ClassNotFoundException: Attempted to load class... Symfony

I start to use Symfony about 5-7 days ago, if my question is very simple, sorry, but I can't find a solution of my problem. I've created 2 form classes - UserType and ClientType. Difference between them is that in ClientType form exists few additional fields. Here is Usertype class:

namespace Acme\Gyvfiles\GyvefileBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class UserType extends AbstractType
{
  public function buildForm(FormBuilderInterface $builder, array $options)
  {
    $builder->add('name', 'text');
    $builder->add('username', 'text');
    $builder->add('email', 'email', array(
        'attr' => array('class'=>'email') ) );
    $builder->add('Password', 'repeated', array(
        'first_name'  => 'password',
        'second_name' => 'confirm',
        'type'        => 'password',
    ));
    $builder->add( 'roles', 'choice', array(
        'choices' => array('ROLE_SYSTEM_ADMIN' => 'System Administrator', 'ROLE_ACCOUNT_ADMIN' => 'Account Manager', 'ROLE_UPLOADER' => 'Uploader'),
        'mapped' => false ) );
    $builder->add('is_active', 'checkbox', array(
        'label'     => 'Active (user can log in)',
        'required'  => false,
    ));
    $builder->add('add_user', 'submit');
}

  public function setDefaultOptions(OptionsResolverInterface $resolver)
  {
      $resolver->setDefaults(array(
        'data_class' => 'Acme\Gyvfiles\GyvefileBundle\Entity\User'
    ));
  }

  public function getName()
  {
    return 'user';
  }
}

And at last ClientType class. All the same, except this part: Update:

<?php
namespace Acme\Gyvfiles\GyvefileBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class ClientType extends AbstractType
{
  public function buildForm(FormBuilderInterface $builder, array $options)
  {
    $builder->add('name', 'text');
    $builder->add('username', 'text');
    $builder->add('email', 'email', array(
        'attr' => array('class'=>'email') ) );
    $builder->add('Password', 'repeated', array(
        'first_name'  => 'password',
        'second_name' => 'confirm',
        'type'        => 'password',
    ));
    $builder->add('address', 'text');
    $builder->add('telephone', 'text');
    $builder->add('internalContactName', 'text');telephone
    $builder->add( 'roles', 'checkbox', array(
        'choices' => array('label' => 'Client can upload', ),
        'required'  => false ) );
    $builder->add('is_active', 'checkbox', array(
        'label'     => 'Active (user can log in)',
        'required'  => false,
    ));
    $builder->add('add_client', 'submit');
  }

  public function setDefaultOptions(OptionsResolverInterface $resolver)
  {
    $resolver->setDefaults(array(
        'data_class' => 'Acme\Gyvfiles\GyvefileBundle\Entity\Client'
    ));
  }

  public function getName()
  {
    return 'client';
  }
}

And after this steps I've used Usertype class in user controller successfully with this statement:

 $objUser = new User();
 $objForm = $this->get( 'form.factory')->create( new UserType(), $objUser ); 

But when I tried to use ClientType in Client Controller with similar syntax:

Update: ClientController

use Acme\Gyvfiles\GyvefileBundle\Entity\Permission;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;
use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Util\StringUtils;

use Acme\Gyvfiles\GyvefileBundle\Entity\Client;
use Acme\Gyvfiles\GyvefileBundle\Form\Type\ClientType;

class ClientController extends Controller
{
  public function addclientAction()
  {
    $em = $this->get( 'doctrine' )->getEntityManager();
    $objClient = new Client();
    $objForm = $this->get( 'form.factory')->create( new ClientType(), $objClient );
    //$objForm->add('address', 'text');
    return $this->render( 'AcmeGyvfilesGyvefileBundle:Client:addclient.html.twig', array(
        'form'  =>  $objForm->createView(),
    ));
  }
}

appears Class not found exception.

"ClassNotFoundException: Attempted to load class "ClientType" from namespace "Acme\Gyvfiles\GyvefileBundle\Form\Type" in C:\wamp\www\Symfony\src\Acme\Gyvfiles\GyvefileBundle\Controller\ClientController.php line 22. Do you need to "use" it from another namespace?"

Can anyone help my with this problem? Thanks!
