[Plugin: podPress] Player widget unable to load playlist

So I have this site, http://louloureyna.com/ that I just loaded podpress on to.
The player widget is installed however it’s displaying an error:

Error opening http://louloureyna.com/wp-content/plugins/podpress/podpress_xspfplaylist.php

When I visit that page I get redirected to http://louloureyna.com/feed/playlist.xspf/ but also get returned a 404

However if I manually visit http://louloureyna.com/?feed=playlist.xspf I get the playlist.

not sure where what I’m doing wrong.

This is a multi-site installation and it working fine on another site on my network, http://agcc.tv/
