Delete songs and Format (Helps with try to delete BAD TRACKS and folders that will not delete
Labeling Unknown Songs: open Windows Media Player and go to library click on artist. The sub folders will be named by the artists and the unknown songs will be in the sub that say's unknown. Click on unknown then right click on the title bar put a check next to artist and album artist. Right click song under artist or album artist or both and type in the name of the artist etc.... This change in your computers Music folders also then sync with your sansa or media player then load songs to it........

same issue, any way to solve this?

You are trying to play a music or movie file that uses DRM copy protection, generally windows media player and other DRM supportive players will try to acquire the license to play the content when you open it. If you are getting this message you eaither do not have the appropriate license to play the file, are not connected to the internet when playing, or their may be a problem with you DRM backup in windows.

I would contact the online store (where you got the file) and ask them about troubleshooting the problem if you believe the DRM license should be valid.

If you got the file from a friend or filesharing service you will not be able to use it and may as well delete it.

DRM, which specifies whether tracks copied from CDs in Windows Media Audio (WMA) format are protected files. A license, which helps protect the copyrights of artists by preventing unauthorized distribution, is required to play protected files.
If you're trying to play your copy-protected files on a new computer, you can migrate your protected music from one computer to another by doing the following:
Windows Media Player 7.1 or later
1.
Try to play the copy-protected file again.
2.
In the message that appears, click the More Information button.
3.
Follow the instructions for migrating your licenses.
Windows Media Player 7
1.
Download the Personal License Update Wizard for Windows Media Player (http://www.microsoft.com/windows/windowsmedia/knowledgecenter/mediaadvice/0048.mspx)and follow the instructions.
2.
Try to play the copy-protected file again.
3.
In the message that appears, click the More Information button.
4.
Follow the instructions for migrating your licenses.
A license can be migrated ten times. After this limit is reached, you will receive an error when you try to migrate the license again (for more information, see the Windows Media Player FAQ). When this occurs, you will need to rip the file from the CD again.
Note If you still have the CD in your possession, you can rip the tracks from the CD again, but with copy protection turned off.

i cant play my music because it says that no license to play from pc

try putting vinigar all over ur computer

try this:-
hold down shift button and right click on any music and go to "open with" and select windows media player to play with...cheers

I went to www.sony.com and was able to find the solution. If your songs were downloaded from services similar to Napster then you will have to log back into the service to refresh the licenses on the songs. If you no longer are subscribing to the service then you will need to delete the songs from your player. If you need further information you can find it on the Sony website.

Need more information, but try this:
There are a few different possibilities.

1)Your subscription to your digital music service such as Napster, etc has expired. Sorry - unless you renew your subscription, you will not be able to play these songs again.
2) Your songs have DRM-encryption on them. To check and see, right click on an individual song name in Windows Media Player, and click on "License" or "Digital Rights"; if the affected songs have DRM encryption, then get DRM-removal software.
3) Your songs do NOT have DRM-encryption on them. In this instance, follow the procedure for item#2, except click on the link in the License or digital Rights tab that says "acquire license" (make sure you are connected to the internet first).

In order to play your song you will need to try to transfer one track to that device...once you do that all the songs should acquire new licenses...you need to transfer tracks to your device once a month in order to play the songs...you should be able to play your purchased tracks....if not you might need to format the device inside WMP....then you need to check the licenses on your purchased tracks to make sure they dont have any restrictions...if you have any [email protected]
