wii monopoly not saving

[GlasgowTitan]

Hey, anybody got this game? We got it the other day and have played it several times and everytime we turn it on after unlocking a new board its not there, it goes back to loading up our one of the first games saying we are on level 1 of the passport but we've played 2 games and unlocked 2 boards yet when we turn it on the next day they are gone???

Its supposed to autosave according to the instruction manual but.....

Any help would be mucho appreciated cheers.
