Kennel Glitch (SPOILERS)

[Guest7]

I make it to the Kennels, and down the dark hallway, following the lights, and when I get to the end door, it opens, I go in, and my game stops.
The dead guy (sitting up against the wall) frame, flickers on and off. Then I have to begin the sequence again. No matter how many times I make it to that room and go inside, the game stops.
How can I fix this. Thanks
PS. I have already downloaded the general Update/Patch.
