Sansa c250 unable to sync music from WMP11

Here is the error I keep getting when I try to sync music from Windows Media Player 11 to my wifes c250.
"It is not possible to obtain device's certificate. Please contact the device manufacturer for a firmware update or for other steps to resolve this problem."
I have updated the c250 firmware to the most recent available and still get the same error. The same error occurred with WMP10 which came with the program.
Any suggestions or help would be greatly appreciated.

The certificate must be obtained by syncing the device to the music service from which you obtained the songs.

How do I get the downloaded music from my computer into the clip?

You have 2 ways to transfer your songs from your computer to your sansa clip:
1. Plug sansa clip to computer, double click on "Sansa Clip ...GB", double click on "Internal Memory", you will see the file "Music", copy your songs and paste them into Music file of the device.
2. Using Windows Media Player: open windows media player, plug sansa clip into computer, click on Sync tab, select songs that you want to sync, drag and drop song selected into "Sync list" on the right side of the windows media player (you should update wmp11), then click on button Start Sync.

Good luck

For 01.xx.xx firmware (c200 version 1) - up to 2GB microSD cards
For 03.xx.xx firmware (c200 version 2) - up to 4GB microSDHC cards
Note: Firmware is not interchangeable.

Manual for c200 series:

Manual for c200v2 series:

For deleting files connect your player with the computer.
When running Windows Media Player 11:

1. Check the automatic SYNC routine for your player.
How to get to the SET UP SYNC
When viewing WMP11 in full mode select SYNC or LIBRARY in the top of WMP11, seeing the Sansa player listed on the left.
Right click on the player and select SET UP SYNC... to go to the SYNC options.

When "Sync this device automatically" is selected, all playlist in the computers' Library will be transferred to the player again, even the previous deleted files. Disable this function to prevent unwanted SYNC.

2. Remove playlists from the library in set up sync, to get the playlists you would like to keep on the player.

Does your player show up as being connected in WMP11
Sync mode ? If not, a firmware installation for the player is needed.

If yes, did you perform doing next actions ?
1. Have WMP11 always on top for "drag and drop" usage
Right click in the head of the WMP11 page:
in Tools > Options... > Player : select "Keep the player on top ..."
Restore Down the size of the WMP11 screen and adjust the size on the
edge(s) as you require for your screen.
2. in [Library] mode: under Playlists "Create Playlist" e.g. "My Playlist"
and Enter: "My Playlist" is added on the right screen side.
3. Open your data maps and ad files by drag and drop method
onto the right saying "Drag items here"
4. when ready adding files in [Library] mode: "Save Playlist"
5. in [Sync] mode drag e.g. "My Playlist" under the connected device
and "Start Sync": wait until al files have synchronized: a message
will show up when you can disconnect the player.

I have a SANSA C250 MP3 player. Trying to sync w/ iTunes.

Put on your ipod and put them on your media player by sync. Itunes can work on the ipod so you use itunes on your ipod and get them.

Sync problem sometimes works and sometimes doesn't

I used Windows Media Player 11 to move music to my Fuze.
  1. Plug your Fuze into an USB port on your computer using the provided adapter cord. Windows will detect the Fuze and install it if need be.
  2. Once Windows has done its thing, open WMP11 and select the "Sync" tab.
  3. You can now drag and drop your music from your Library on the left to your Sync Playlist on the right.
  4. Once you've moved your selections, click on the "Start Sync" button at the bottom of the right side.
  5. The music will be uploaded to your Fuze.
You can have WMP11 detect your music and put it into your Library by pressing the F3 key. Press F3, navigate to your music folder with the Add button, and then press OK. You can remove folders from the list in the same manner.

Help with syncing music to my comp frm my mp3

Generally, you can move music from Windows Media Player to yur mp3 player, but not the other way around. Press the sync button, and set up a sync profile for your mp3 player - then it should recognize the songs that are on there. If that fails, I would reformat the player inside of Windows Media Player to see if that helps any.

Have fun!

Cant download music

The songs need to be formatted for a sansa. Use Windows Media Player 11. Don't use Rhapsody, too many problems.
Load a CD into your computer, on the Toolbar of WMP11 click rip, After all songs are ripped, hook up your Sansa to the computer via USB cable, Click Sync. WMP11 will not only sync the sansa it will sync the micro card also. You have your choice where you want to put the music. Drag and drop the music in the box to the left where you synced your sansa and at the bottom of the box click Sync. All music will be synced to your sansa or card which ever one you chose. Understand, when the sansa starts up, the card syncs with the sansa, you don't have to do anything. Try this and let me know how it works.

Loading music

What are you using to load music. If you have access to Windows Media Player 11 it is very simple.

First open WMP11, make sure your player is connected to the computer with the USB cable. At the top of WMP11 click Sync
the player will sync with WMP11, drag and drop music and click sync, very simple. I have a Sansa View and it is very simple, This basically works with most MP3 players.

Unable to sync music

What happened when you tried to sync? it could be a device certificate error...what i would recommend you to do is to sync using your windows media player...assuming that you have windows media player up your windows media player and click on sync..then you can drag the tracks you want to sync and then click on start sync...if you are not able to transfer the songs to it..use a song that is not from yahoo like the sample one that came with your computer and see what happen...if that doesnt solve the problem check your usb should be under MTP mode or auto....then open up your windows media player and format the device there...after you have done that..that should solve the problem you are having..let me know what the outcome is....
