So you wont help me because you ar all under the suspicision that I pirated the game?
Pretty much.
FO:NV usually installs under C:\Program Files\Steam\SteamApps\common
Your copy is installed under
That's NOT normal, especially since Steam will install to those folders without asking if you want to change folders. And before you ask, my version of New Vegas is retail.
In fact, looking through your topics, it seems like many of your problems may come from the fact that your game is pirated (if it is, indeed, so.)
If you pirated it, why not just buy it legitamately? It's about $30 off of Steam for the ultimate edition.
