1. Have your league members in question go to their data/saved_games folder and completely delete the entire league file, folder and all.
2. Have the commissioner of the league copy ONLY the .DAT files for the league and place them into another empty folder named the same as your league folder(i.e. bigleague.lg). Zip it and give it to all the league members having issues.
3. League members in question should unzip and copy the whole folder (i.e."bigleague.lg") into their data/saved_games folder
4. Fire up the game and open the the league.
That will work.
