yea, im running vist atm, basicly your ini folder is read only, but then again so is ur co2.0 folder, and on top of that shit. . .if you change it, you will notice that it doesnt really change, due to the security settings put in place by vista predetermining what files which user has the option to modify. play in the security tab of the conquer2.0 folders property section and make it so you(the user) can modify the whole file tree beneath this folder and then you wont have a problem. I just did it no and it was a pain cause im still new to vista, but the more i useit the more i realize how the good far outweighs the bad and how much more powerful vista is then xp. woot vista?? na, i wont go there just yet lol.
