I was running firebird on firefox to look at load times for my site when I detected a 404 error from a call for the following file:
/plugins/ssg-google-audio-player/swfobject/swfobject.js
The call happens twice in the ssg_google_audio.php file. But the plugin actually installs to a different directory:
/plugins/ssg-wordpress-google-audio-player/
Please note this bug for future versions.
