HELP PLAYERS BIRTH YEAR PLZ HELP

OK Im playing a 1997 patchi thought HJordans fun but no Magic so i wanted to bring magic back but he would be 43 or 44 and he would retire and i wanted to keep him around for couple of seasons.

I tried to make him younger in Player Edit but since he came with the game i cant there its a big white bar so i cant click on it How did i edit Magic birth year.

You can't edit the birthdate of a player through the "Edit Player" menu.
Instead, try to edit PLAYERS.DBF file (BIRTHDATE field).

i do i do that or load that file
