I got a black screen that froze my comp earlier,
I ctlr-alt-deleted to open task manager, after about 2minutes, the PC stopped hanging and let me join the game. This only happened to me on the multiplayer page of FH2, so I tried using the FH toolbox to connect to a game and lo and behold, it worked for me. ( it did take a while to load the game through the toolbox but I haven't gotten any hang ups from it yet).
