I have several players who are listed as "inactive". No matter what I do, I cannot activate these players. Why?
Perhaps you have PERMANENTLY replaced a golfer with another player. For example, if you are in event #5 and PERMANENTLY REPLACE John Doe with a new player, John will be marked as inactive in events 1,2,3,4 since he is no longer participating in the league.
For more information, please refer to Making A Player Inactive.
