FYI, I was getting this error in the previous version as well on this MP3:
http://the-adventurers-club.typepad....eeper_tone.mp3
(I don't use BSPlayer for MP3s usually so I can't say if the error is specific to that MP3 or if it's all MP3s. But I thought it might help someone troubleshoot to have an actual MP3 that creates the error)
