M260 Series - Problems with making a playlist??

I was using my Windows Media Player to manage my songs and playlists.  However, in recent weeks, my MP3 play would not make a playlist, although it showed on WMP that there was one.  After trying various programs, the one that seems to work is WinAmp. 

Hope this helps some of you. 

I have to say, it really is disappointing that my Sansa M260 would be such a chore to use.  Needless to say, I just bought an IPOD.

Peace at last!
