You can play Superstar-mode only once!?

Hey EA, what is this? I play Madden only for the Superstar mode, bought it, started the mode, accidentally simulated the combine.. Wanted to star over, but.... YOU CAN'T!??? I'm on PC/EA app, and you can only create ONE superstar!? So even if you didn't mess up somehow, you can play it ONCE!!?? So you are not able to try other positions and even if you play the game through and retire, you can't play again? So for 70€ you can play once.... What is this!? I know people hate on Madden because of all the bugs etc and for sure even the Superstar mode has gone worse every year from the times you could play any position, hire agents etc, but this takes the cake. Only one game, and if you mess it up, that's that. No way. Fix this please or at least mention this in the description as a new feature!!
