ive had my wii for just 3 days and all of a sudden my wiimote stopped working correctly. When im in the main menu i can move the cursor around and all the buttons work but when i go onto wiisports it wont detect my movement. its the same on 2 other games aswell......ive done all the syncing and ive even formatted it in the hope it would work right again but its still the same.............is it my sensor or my wiimote thats broke??? please help and thx in advance
