Oh dang, that's very odd. When you would click newgame, would nothing happen and the continue button would take you to the map screen but nothing there would work, correct? Or was it the game just wasn't working or crashing? I can only suggest uninstalling and reinstalling the game and if that doesn't work, I'm not quite sure what else could be causing your issue besides a corrupted save file. I'm so sorry I can't be of much help!
