If you've received the latest Steam update for New Vegas and you're having issues starting the game, try re-verifying the files.
1) Open Steam
2) Right click on Fallout: New Vegas
3) Hit Properties
4) Click the "Local Files" tab
5) Click on "Verify Integrity of Game Cache"
If that doesn't work, delete your ini files and repeat steps 1-5

How do I find these files to delete them? (each time I perform steps 1-5 it says "1 files failed to validate and will be reaquired" but it never is, appearently.)
