Superstar Mode Error

Unfortunately, the Superstar mod has never worked well for me. After buying the game at launch, I could never get into it. When I tried to start the game in Superstar mod mode, the entire Madden application would crash. Now, after the latest update, I can at least play with it, but there's a problem. In the league settings, I set quarters to 12 minutes, but when I start the game, they're only 6 minutes long. Has anyone else encountered this issue? Is there a solution?
