Without spoiling things to bad im at that part. Iv re-loaded at least 3 times from right outside the coffin, and tried twice reloading after leaving the dinner part. But for some reason it keeps freezing during the blackout part. Iv waited at least 15 minutes for it but it wont load.
Any advice??

Save inside the coffin when you hear "sleep" and then use that save to reload if your xbox freezes. Usually restarting your Xbox and loading this save will get you through. Some people say to wait, but I find that you don't need to wait, your xbox will either freeze or it won't, and if it doesn't, then it only takes 1-2 minutes to get out.
