Symfony2 - PUGXMultiUserBundle - Cannot instantiate abstract class - symfony

Question

I tried to install PUGXMultiUserBundle, now as I did all steps I tried to load the application (only the main location: http://localhost/jpp/web/app_dev.php ), but I always get the following error:
Fatal error: Cannot instantiate abstract class JPP\UserBundle\Entity\User in C:\xampp\htdocs\JPP\vendor\symfony\symfony\src\Symfony\Component\Security\Core\Authentication\Token\AbstractToken.php on line 155
I tried several things without success, please could you help me? Below you can find my Entity classes. I was able to create all the tables in the database with GIT. The rentity classes are located under: JPP/UserBundle/Entity. If you need more files please tell me... Thank you very much!!!

The error says:
Fatal error: Cannot instantiate abstract class JPP\UserBundle\Entity\User in C:\xampp\htdocs\JPP\vendor\symfony\symfony\src\Symfony\Component\Security\Core\Authentication\Token\AbstractToken.php on line 155
It means that Symfony tries to instantiante your User class (e.g. new User()) but fails because this class is abstract. So, just remove abstract definition.
Replace
abstract class User extends BaseUser
with
class User extends BaseUser
