could be a number of things.. depending on what game your playing they have preset macros that you can restore on your mse program. All you have to do is go under your settings and on the bottom left click restore, the file should be under the same folder as your MSE itll be labeled configpack these config packs have a number on the side of them thatll let you know what sensitivity to set it to in game with that said if the game your playing is not in the configpack folder then youd have to manually set it up your self through weapons database
