Plutonium

Does anyone know if there's a way to change ADS sensitivity? I just really like to keep my hipfire and ADS sensitivity at 1:1.

H3X1C Deleting the game folder doesn't prompt the client to go through the whole process of reinstalling everything related to plutonium into mw3 folder. How do we get that to happen again? Because clicking the gear button to the right of the play button does not work? (Clicking it doesn't do anything)
