hi i'm new to wii. I am having a problem with wii play. every time i select 2 players the console freezes, and the only way i can unfreeze it is to unplug the power. power button and reset buttons wont work. all other games work fine. have setup 2 controllers. was bought second hand, previous owner said he never had a problem. latest upgrade has ben installed. it is frustrating as all i want to do is beat my wife in snooker. can anybody help????
