Hello, has anyone had any issues with their magic remote not working and know a fix? Mine won't pair or unpair, I've tried new batteries and unplugging the tv with no success. The cursor is greyed out with a 'no entry' sign and occasionally a 'quick start' grid appears on screen but I can't access it as the remote doesn't function. It was ready for the latest update but I hadn't downloaded. Any help would be greatly appreciated. Regards Andy
