Quitting issues since installing patch

[Samirus]

Before I had to install the latest patch the game quit fine without any problems, however upon installing the patch this is not the case. Everytime I quit the game my computer locks up, the taskbar and stuff is displayed but where Steam once was I get a black window, along with a window roughly the same size as the SDK main menu different coloured. Anyone have any ideas why this is?

Have you verified your game cache files? (Right click on Sin Episodes in the Steam games list, pick Properties, pick Local Files, pick Verify integrity of game cache)

Yep that seems to have fixed it thanks alot Michael. I would of never thought of doing that as i've only just re-installed the game.
