this is my first post been looking on here for a while but i have a promblem i am quite far in to the game but everytime i got to the lucky 38 or the hoover dam my xbox freezes. i can play as long as i want everywhere elese but if go to a certain point in the dam it freezes or if i get to the top of the lucky 38 it freezes as well. i got the game when it first came out so i dont know if i will be able to get a new disc but if i do will i still have the promblem becuase of the saves i have made in the first game. i really cba to start all over again.
