Resetting Level??

Hey guys,

I joined 1 of these prestiege lobbies by accident...
And was wondering if there is anyway to reset level as i would like to have something to do in this game.
Rank hacking in mw2 made the game crap...
So does anyone know how to reset their level or could someone help me figure it out.

Thanks for reading.

If you have any ideas post!

just delete them like the way we did in mw2.

where are they but?
i looked in players and my user file bit and theres nothing their but config
