So i have finished the main quest in OWB, now every time i try to use the teleporter gun to go to NV the loading screen appears and the wheel goes around 3 times and then my game freezes. I have tried shutting hardcoe mode off, and autosave to no avail. I have even installed the game, and tried with two different game discs, it freezes my console after 3 wheel turns of the roulette wheel. I have all patches available online. Please somebody help me.
