Re: controlssettings
I made a similar mistake.
Go to (Drive Letter):\Documents\Criterion Games\Need For Speed(TM) Most Wanted\Save\
There is another foler with some numbers for name, open it.
Inside that folder you should see 2 files. Delete the "controls.NFS13Save" file.
Start the game and all of your controls will be back to default.
Hope that helps.
