Sansa e250 dispyaying synchronize to continue music subscription

What do you guys use to downlad the files?

Here's the deal with WMA files - once your subscription expires (or really,  the license on the WMA file expires) - you will have to renew your music service subscription or the song will no longer play on your device. 
Use Mp3 format songs - they'll never give you this problem.

renew your subscription, then reload the songs onto there

Maybe you should mention that if you format, it will delete all your songs?

Well...when ever I sync songs to my Sansa. I never change the mode and it syncs FINE! You should try it

Download the Sansa updater. It worked for me.

first you must format the player using msc mode then after that retransfer the songs to the player. If you are receiving this message it means that the songs on the player have expired. This is normal if you download the songs off rhapsody, napster or any online music stores and if you have ripped songs iwht copy protect music on it if you ripped them using windows media player 10.

Do you have an account with Rhapsody? The preloaded music is part of the Rhapsody subscription service. If you dont have an account, you will receive that message until you delete the preloaded music, or subscribe to the Rhapsody Service. Best of Luck.

Renew your Napster sub- resync

Do you have Rhaposody? I had this happen to me. If you have Rhaposdy try reauthorizing your device. This worked for me. If this doesnt work, try contacting Rhapsody or Sansa.
