Hi All, I have just started playing Fallout NV, and fairly quickly stumbled into the Dead Money add-on. I have played through the scnario to the point where Dog/God, Dean and Christine are all at their correct positions in the Switching Station / Rooftop etc. I head East from the fountain and eventually come to a door at the top of some steps whcih I have to go through. Everytime I try to enter, the system crashes. I have a 6 core i7 Intel processor, 32 Gb RAM, nVidia GeForce GT680 (with new drivers) and a fully patched and up to date system. I have tried this numerous times including picking up more objects before retrying the door - with no success. I have "verified game integrity" within Steam. I cannot go any further and am loathe to abandon the mission by going to a previous saved game as this has already taken me a few hours!! Any ideas?
