When I attempt to launch Ep2 on steam roughly 1/4 of the screen turns white. I waited about 10 minutes hoping that it would launch but it didn't.
During that time I heard music playing which I assume to be the main menu. I started it again a few times but nothing happened. Just so you know Episode 1 worked perfectly, as has the other Telltale games that I received when I bought the W&G season.
