Mycareer file corrupted

Is there anyway i can transfer all of my data in my corrupted MC save so it can load again? Using RED MC? I am in my 2nd season
and i badly need so i can play with my old MC

You can try starting a new game and then copying the data over with RED MC, but there's no guarantee it'll work. Quite often when there's a corruption in the data, there's no choice but to restore from a backup if possible, or otherwise write off the file as a goner.
