Podpress player only shows "loading"

I can’t seem to figure out how to get my player to actually play the mp3 podcast. It just says “loading”. I am a newbie to WordPress and podcasting so I am sure that I am missing something.

I have my podcast locations where it creates a drop down box in the actual post section of my website.

I am using “responsive” wordpress theme. I have read other threads where this could have been the issue. HTML is still very much over my head but I will try anything to get this to work.thanks.
