Thanks Shane,
I did read that mate but my disc works but NOT when there's a ball on the disc magnet for some strange reason-I did a factory reset and it worked once with a ball on the disc magnet then not after that its real wierd. During MB when the balls are on the magnet and the disc is meant to spin it doesn't but when the balls just fall off the disc it will then start to spin so the conclusion I've come to is it won't spin when there's a ball magnifiyed to the disc buts it should and when there's no balls on the magnet on the disc it will spin its got me buggered
