PC: Problem mit Enemy Territory Quake Wars

Immer wenn ich das spiel starten kommt das bei Enemy Territory Quake Wars: Another game instance is already running.
Use win_allowMultiple Instance to force.

und danach kommt: The Open driver dosen´t support wglChoosePixel FormaatARB.

Und dann öffnet sich eine Konosle wo das drin steht:
