[Plugin: HTML5 jQuery Audio Player] player won't load

Hi there,

I totally fell in love with your audioplayer plugin for WordPress. After I’ve installed it, it worked like a charm. But after a few reloads in Firefox and Safari the player suddenly didn’t show up on my website anymore.

The Player should show up on this page:

Could you please help me out, what happened?
