Help!!! reopening playlist problem
 

I am having an odd problem.. I have no problem opening saved playlists thru LimeWire UNLESS I have added any songs to the playlist after the playlist was first saved. Example: If I need to add a song to one of my saved playlists, I "open" the saved playlist, then I "Enqueue" the song to the opened playlist. I then "Save" the revised playlist & just keep the playlist name the same as it was (I overite the old one)... However, later when I try to reopen the same playlist, I can select the playlist file, however NOTHING shows on the playlist songs. I can however still open the playlist fine thru WinAmp, etc. & still play the songs as usual thru it... just can no longer get any songs to show in the LimeWire playlist now.
Any Clues... or is it something simple & I'm just stoopid?
