Couldnt unfreeze my mp3 player and your advice worked now

Find the reset button and press it for 10 seconds at least until it reboots the player, hope this helps.

TRY CONECTING IT TO UR COMPUTER IF UR COMPUTER RECONIZE IT THEN ERASE ALL UR SONGS IN PROBABLY ONEOF THE SONGS U PUT IN WAS CURRUPTED TRY THAT FIRST

take the songs you want off the mp3 copy and paste drag to desktop or your music folder and se if that works if not reboot comp rinse and repeat

just format it then put all music in again or just sync

mormontazzy, plug in your sansa e200 then go to "my computer" on your computer find an icon that says sansa e 200(it might say sansa e250) click on it and go to a file that appears that says media then click on the songs file after that get all of your songs from itunes and drop them into this file if tat doesn't work then take all of your songs from itunes and dropping them into widows media player

Put those songs into the My Music folder in your computer. Then open Windows Media Player, and give Windows Media Player a couple of minutes to re-read the songs. then Sync those songs to your player using Windows Media Player.

Actually after some searching it is VERY easy to manage the c250, you just have to know how to connect it. You must connect it to read as MSC format. To do this, put on the hold feature and press and hold the rewind/previous track button as you connect it. This will open it up as a removable disc. So just drag and drop whichever songs you want from the MUSIC folder. You may also delete individual songs that are already on there. Hope this helps, works for me.

This means that the MP3 file does not comply with the WALKMAN. Make sure that your MP3 file is:

• MPEG-1 Audio Layer 3
• Sampling frequency : 44.1MHZ
• Bit rate : 32 to 320kpbs, variable bit rate compliant.

I ended up being able to format the device using Windows Media Player. I had several songs I could not delete because they became read only somehow. ??? No new firmware for my MP-C543, either. But, that worked.. Plug in, right click the device and choose Format..

Hope this helps..

Dear sir if you use windows media player and sync the music it will work. click dragging the music into the players memory does not work.
