Hello, I am unable to finish Fallout New Vegas to my liking due to a number of bugs that are stopping my from accessing areas in the game in particular, Nelis air port which if I do manage to enter I can't leave the room without the loading freezing. Also the Crimson caravan compound cannot be entered since the loading screen freezes. I cannot get to boulder city for the game freezes/ crashes when I get near it which is the same problem I have when I get near the Repconn building which has stopped me from complete a number of quests!
Please help me I've been struggling with these problems for some time and now I'm at my wits end!
