Music Shield not playing

Greetings and salutations. This is my first post.



I just got a Seeedstudio Music Shield a couple of days ago. I have it plugged into an Arduino Uno and have been trying to compile the example programs.



I have gotten the following errors:



This error is from MusicPlayWithName:

This error is from MusicPlayRandomly:

This error is from MusicPlayAlll:

I have searched the content I downloaded and unziped and the term ‘traverseDir’ does not show up so it is no wonder that it is not found.



So can anyone help me get this running?
