As editor, I have no control over the store (it's a 'site owner' function) and can't tell if something's broken there or not. I only know the mp3's not missing. If you've paid several times, only Wayne can detect it, send you the mp3 and refund whatever extra you paid. I'll send him a mail about it.
The tricky bit is getting a response. I'll give it a shot anyway. ...Message sent.
