So Im at gideons house trying to cross the chandalier to get to the center. i drop the chandalier, use the long railing and every time i do that the game crashes to desktop. i cannot for the life of me figure this out. any help would be appreciated. I am running Windows 7 Home Premium 64-bit on a Pentium q8200 quad-core CPU, gigabyte motherboard(can't remember exact model), and a XFX Nvidea GTS250 card. thanks in advance
