help using toolkit

used the toolkit a few days ago to edit rosters, i screwed them up so bad that i reinstalled

now when i try it i get an error!

i installed the game to c:\program files\ea sports\nba live 2003

there is also a folder c:documents and settings\my name\my documents\nba live 2003

last time i had the toolkit in the program files, and selected live files-the folder 'saves' from my 'documents and settings' folder, then went to megamodifier

now when i go to the megamodifier it gives me an error

anyone remember how to use the 97 ms toolkit(it does work for 03)

what am i doing wrong?

thanks
m.i. out
