There's a thread around here for that somewhere, I'll dig it up and post the link.
If I recall, the issue is with a corrupted user profile save, and the gist of the solution is a couple of steps -
1 - always let the game auto-save the user profile
2 - never save the user profile manually
3 - ensure that the game is not auto-saving when you exit Madden or power down your console
4 - you may need to delete your user profile and re-create it
EDIT: here's the thread on the subject, please continue discussion of the issue here:
