Steam Game not showing up

I installed World of Tanks Blitz with the Wine Steam runner, the installation finished with no problems.
When I tried to start the game, Steam tells me the game is running, but the game did not open a new window. In the system monitor I saw that a new process was opened up though. No error message popped up. Can someone please help me?
