There is a sample skin that shows a basic implementation of the plugin. By basic, I mean it shows you a web page and a couple working buttons, but it does not give you any song info. I tried adding a couple more buttons for Next and Previous, but even following the form that was already there, I failed. I could get the buttons to show up, but for whatever reason the script didn't work.
Oh, and I still can't get the plugin to work reliably. The old version worked pretty well, but this version keeps giving me the error I posted above. I can get it to work maybe 1 of 10 times. Not sure what I'm doing wrong. I've tried Firefox, IE8, and IE on my IPaq (PPC 2002 so it's PIE or Pocket Internet Explorer which is probably IE 5 or 6 compatible).
