I just go a Wii and picked up Super Hero Squad (not Infinity Gauntlet) for my kids. The problem is it doesn't appear to save their progress. They can play for 2 hours and make it through several levels, and the next time they turn it on, they have to start from the very beginning again. I've even played through 4 or 5 levels and the same happens to me. Also I can't seem to get the characters unlocked. I enter the code to unlock the Black Spidey or different Wolverine, but when I go to Battle Mode, I don't see them. Is there a way I can cycle through the different costumes of the characters? Please help. My kids really like this game but are getting tired of playing the same levels over and over.
