After clearing the first pirate fort "blow me down", there is a cutscene when you are heading towards Nekata. After that, there's a below decks scene and your first opportunity to talk to your crew. After talking to everyone and walking outside, the game is crashing to desktop but the game window stays "active". I can hear the sound and even click around on the screen but all I am seeing is my desktop. Alt-tab, changing resolution doesn't bring the window 'back' to a state where I can actually manipulate the game. I'm on Windows 7 and I've tried 4 different sets of Nvidia drivers. Any ideas? Didn't experience any crashes prior to this!
