Yeah, I don't know what's up with the zip file, particularly on PC. I thought it was something weird with my config, but if others are having the download/extract problem, then something else is up. I actually had to unzip it on my Mac, then transport the files over my network to my PC. Ridiculous.I have to be honest, I've all but given up on the Seeed board. It wasted so much time. I spent several hours trying to get it to work from my MacBook. All I ever got was MP3 playback. Then another several hours on my PC - hoping that a completely new Arduino IDE environment would help. I followed all of their instructions (as best I could - they are terribly written). I could still get nothing more than the MP3 playback, no reliable WAV. But experience with some other boards - like Rugged Shield - shows that my WAVs may have some meta data that these shields don't like, so I might go back to that.http://www.shivasongster.com/2013/03/rugged-audio-shield/If you like I can send you what I have for the Seeed via Dropbox.
