i bought New Vegas at the midnight release, went home, played 1 hour of it, and i didnt really like it. so i have just recently started playing it again because HEY I PAID $50. so the game works fine i guess but whenever i scan the game to see if everything is there, there is always a file missing....yes i use Steam. steam wont let me figure out what file is missing and wont tell me what to do about it....what do i do?
