No recoil

Hey guys

I was wondering if someone could help
when in ollydbg I search for FireWeapon I get this error
unable to read memory of debugged process.

when you load the file, first hit "F9" so it will compile it in memory, then do the search so it will show all correct strings, or else it doesn't show everything

thanks for the help I did do it this way but I still get recoil in BO do you know of any other way that I can try to make less recoil or no recoil at all
