In Five Oh Sink when i kill the guard in the chuch tower i proceed up the stairs to the Loading... here my computer crashes, any tips? thanks.

OK, after going up the stairs and around the hole in the floor, you go down the next hall a little bit and you find another room, turning right I believe is the bathroom where there is a tub. I don't recall seeing the ramp or anything else. So what do I do? By the way, feel free to email me at prersoil@yahoo.com.
