My wife and I beat the game on easy mode, I waited for all the credits and cutscenes to finish so I could save the game and it won't let me start a game on Hard mode. Am I doing something wrong? Did I miss something? Or does the game have to be beaten on normal mode to unlock hard. Everything I can find says it will unlock after easy or hard. Did anyone else have this problem? Also if it matters I am playing on the Wii.

Thanks in advance for any help.
