Today, after making no changes to the game since I last played it (nor my system, to my knowledge), when trying to launch the game, a black screen opens up, the mouse switches to a loading icon for a moment, then the mouse switches back to a pointer but the screen remains black, not starting the file loading sequence or showing any graphics. I have to 'end task' to shut it down. KSP_Data output_log Hopefully that's all the info you guys need to help with this problem.
