Premium not unlocking! Please verify.

I bought the premium version, but it felt too short. I completed the map in less than two hours, and there's no more content. There's a great variety of characters, though. It would be fantastic if they added more maps.

I put a controller (xbox one), the controller is recognized, but when I select two players, I can select the first player with the keyboard and mouse, but the second player's controller is not recognized.

it doesn't work
