Have tried to play a couple of games on the Wii recently, and my scores are just not registering (so it's as if it doesn't know I'm there playing). I've changed the batteries in the remote control thingumy and that has made no difference. I wondered if it was to do with the sensor that you put on top of the screen, but then I'm able to get into the games with the remote - so I guess it must be working. Drawn a blank. Any ideas? Thanks
