Madden 2004: Problem using edited historic teams
 

In Madden NFL 2004, I'm having trouble trying to play a game using edited historic teams. I'm able to edit the rosters (to add in the players' names) and it saves the changes. But when I go to play a game with that historic team, the players have their generic uniform numbers again (with none of the changes that I made). I don't know what I'm doing wrong... Can anyone help?
