I have a Nokia C601 with belle and my songs on the memory card. Suddenly one day the player does not show the song list. It does the albums but when you try to load the songs it says something like "damaged/corrupted file". Is I surf the file system and choose a mp3 file I can ply it no problem. Any clue? I tried to re-install the belle, but the problem still there. How could I re-install only the Player?
Welcome to the Nokia Forum!
Have you tried to refresh your music library? You can do this by going to the Music player main view and select Options > Refresh library.
You can also try to perform a soft reset using the code *#7780# using security code 12345 by default if prompted. This will not delete any of your data, only restore the mobile settings to as they where when new.
I hope this has helped, please let me know if this has resolved your issue or not.
If you have access to a PC you can create a copy of the memory card on your PC and reformat yoru memory card inside the device.
Once it has been formatted, plug it back into your PC and restore the backup.
I hope that it works!
