Plutonium

So I was playing around with the fire rate command and the melee rate command and now i can't put it back as it once was.

Pls Help

when the game started did you try to restart the game by going in the command prompt and typing 'fast_restart' without quotes.

The settings are always resetting I tried to run it as admin but it did not work. Its starting to get very annoying cuz I'm trying to play the bo1 campaign and my saves are also gone . I have to redo my controls and my graphics so does anyone here got a solution for this problem.
