I am having a problem with my car warping out online. I am wondering if it
is a problem with my ISP, or if I have issues running the game with VISTA.
Anyone else having similar problems?

I am having the same problem

The problem i keep having is that the DEP settings will not allow me to
change them. The issue is the the game loads, plays it's intro, plays
everything else, but when it comes time to get into the car and "drive" the
game says it stoips responding and that the dep is active. can someone tell
me how to fix this. i just upgraded from xp to vista ultimate x32, and i
would hate to have to make the change back over to xp. although it is temping
already due to vista's extreme bugginess.
