I can't resign my star player.

Apparently I don't have enough money to resign Kevin Garnett again. Is there a way I can sign him...perhaps through DB Pro editing?

u can release some expensive old bastards and grab KG, + some new cheap guys!

Depending on where you're up to in the game you can change his years he has signed for up to seven years so he won't go out of contract with you anyway. Make sure Years_left is less than Years_sign or even better the same ie seven and seven, then you've got him for, you guessed it seven years.
