mp3's hosed again

["J.Moore" <listreader1 cullmail com>]

I recently upgraded to FC5 (from FC4). I followed the instructions in
the Sound Juicer help file to add mp3 to the list of available formats,
and immediately ripped a new CD. However, when I try to play the .mp3
files in Audio Player, it refuses to play. The "old" mp3 files still
play in Audio Player just fine.

I know this must be the oldest and tiredest question, but how do I get
Audio Player to play the "new" mp3 files?

Thanks,
Jay
