Most don't know how to install or update such.
I installed the game, I can start it, it plays fine...until I get to the territory controlled by the 21st Street Crew. That's where the races start quitting as soon as I complete them about 89%-95%. Why? Somebody told me it has something to do with my virus protection. I turned that off. In fact I turned off every other program I had running and even disabled my internet connection. It still doesn't help. What can I do? I know I got the right hardware to play the game because I've played all the other Need for Speed games on it and my computer way exceeds the requirements:
Intel Core 2 Duo E6600
Diamond ATI x1300 video card
2 GB RAM
