I can suggest you copy/paste the following into a brand new empty text file, then you save it in the same forlder and name it "config.mw3esp".
Code:

// Settings file for MW3 .NET External ESP by master131

// How often in milliseconds to render/draw on the overlay.
// Decreasing will make it render faster but will use more
// CPU power. Increasing will do the opposite. Play around
// with this to optimize the performance of the hack.
RENDER_INTERVAL = 20
// Overrides the sensitivity that is read from the game.
// Only change this if for some reason, the aimbot does not
// work. Set the value to the same value as the one seen
// for 'sensitivity' in config_mp.cfg (without the quotes)
SENSITIVITY_OVERRIDE =
// Overrides the name used to create the executable in the temporary
// directory. Leave this empty to let the Launcher randomly generate
// a name but if your Anti-Virus does not like it, give it a name
// and then add the file to exclusions when it detects it as a virus again.
// An example would be "abc123", remember to add the quotes.
