Wii fit problem

Question

Hi thanks for trying to fix my problem. We have done the update on the wii before we bought the wii fit. the game did load but when it checked the time and date we noticed the time was wrong and re-set it. from then on the disc would not load. I have tried it in my friend's machine and it loads in theirs no problem. All our other games still play so I am at a complete loss as to why this one won't.
