I also had that issue at one point, I just kept trying everything callme.nasty recommended and it eventually worked. If it doesn't just take his advice and return the game. I worked at best buy so as long as the game is defective they have to exchange it for you.
Hi We bought the game today and also have the same problem (can't get more that one wiimote to connect).
We've reset the console with game in, changed batteries and tried coniguration with game in but still no luck.
BTW other wiimotes work fine in wii play and wii sports..
