question about db DBC

I want to make chris paul into playmaker so i used the way in one of the sticky topics up here (change the vlaidsstar with dbc in players.dbf)
but after i changed it, how do i save it/make it work?

You'll need to change both VALIDSSTAR and SUPERSTAR, to ensure he's both capable of being a Playmaker and his Playmaker FSS is enabled.

thanks a lot
