Hello, I bought a Wii for the kids for Christmas, all's working fine except for 1 problem. On the Wii sports Bowling game we cant let go of the ball. All of us have tried, press A to pick up the ball, press B to play the shot, let go of B ........the ball goes backwards???? I've tried re-syncing the remotes, changing the batteries, switching on and off and moving the sensor bar. Any ideas welcome.
