Music Shield not playing

Hi,



I have checked that many times already that the name of the file on the card matches the name in the sketch. I see I am not the only one who can’t get the code to work to play a single file by hame. Not sure what to do now, it’s not much use without being able to play individual track, has limited funtionalilty. Has anyone managed to make the shield work with any of the demo code apart from the Demo 1 which does work?
