Question about Sony NWZ-E436F MP3 Player
The license on the songs that you have transferred to your mp3 player have an expired DRM license. The only way to "unexpire" the license is to refresh your license through the music service that you downloaded the songs from. If you have let your subscription lapse, the licenses will stay expired.

Are the files MP3 files or WMA files? This sounds like a DRM (digital rights management) limitation of the music you are using. MP3 files don't have DRM - and shouldn't exhibit this problem. WMA files can have licenses associated with them and only allow number of copies to be made for personal use before their license disables further use - as it sounds is occurring in your case.

The license on the songs has expired, and that's the problem with DRM-protected WMA's. You will need to renew the license through the music service from which you downloaded the songs. If your subscription has lapsed, you will need to renew it. Then, you'll have to delete the songs on your Walkman, and reload them once you have updated the license.
If you only download and transfer files in mp3 format you will never have this problem, and you can keep the songs forever.

do you still pay for your napster service, if not, that why your tracks have expired, if you do, then just hook up your mp3 player to your PC and it should update the licenses on the tracks
if you dont pay for napster anymore, one thing that maybe worth trying is setting the clock on your PC back to a date prior to the subscription expiration date and try playing a few songs without being connected to the internet. If the PC is not online, Windows has no way of telling if the time change is to correct a wrong time or deliberate.
I am not sure what Windows Media Player does when the expiration comes. If it modifies the song itself, then it may still be possible to play songs that you haven't tried playing after the expiration date if you set the clock back.
However, if Windows Media Player logs that the licenses have expired in its license database, then there is pretty much no hope in reactivating them by setting the clock back. Much like setting the clock back on expired shareware software
Finally, if you are willing to resume your Napster subscription, then chances are that your music will re-activate once your subscription is live.
