My little boys birthday is tomorrow and I am having trouble setting up his new Wii. Last night it was working fine but this evening when I have tried to set ujp a second controler it is not registering. I have gone through the setting up procedures again, checked the batteries etc but when I point the controllers I get no response from either!! Any Ideas anyone as he is having a Wii party tomorrow at 1.00pm and I will have 8 unhappy dids if I can't get it working!!! Help!! Is there anything I couyld have done to the sensor bar?
