[Plugin: MP3-jPlayer] Upgrade Issue in 1.7.1

I am upgrading my MP3-jplayer from 1.4.3 to 1.7.1 for the added pop out functionality but have run into an issue.

Currently I run a music website were every page has a playlist, so in custom fields I use the “1 mp3.Artist Name” as a name and then for the value I put “Title@URL”and do this for however many songs I have. This has worked well for all my posts without a hitch. But as soon as I apply the 1.7.1 version it breaks all my players I’ve made on my previous posts. The unusual thing is, I can still create new posts with working 1.7.1 players but all my players I created when I was using 1.4.3 are now blank (the custom fields and everything else about those previous posts’ remain the same) just seems the new mp3-jplayer isn’t reading them correctly.

Anyone have any suggestions what it might be?
