* MP3 Shield * - Rogue Robotics rMP3

Just been trying to get it even playing an mp3, and it never compiles. Just gets the same error every time.

And I have no idea why it is not working. I have downloaded, and installed the serials library change, and selected the [stream] uno module.

Any ideas what the issue might be?
