I bought EA Sports NHL 2009 twice (first new, took it back, just bought it used). On both disc's I get through the first season on Dynasty Mode and than at some point while it's simulating (usually right after the playoffs or right before the draft) it freezes up. The music keeps going and I can change the songs and the simulation bar is still rolling. I've turned off my PS2 and started a new Dynasty and it does nothing. Neither of the disc's were scratched and every other game works fine. Any suggestions on how to make it work?
