I JUST GO MY sansa e200 TWO DAYS AGO AND I OPENED IT YESTERDAY

I'm not sure of your problem exactly but here is what I found!

This is your manual for the MP3 unit you have. On page 14 it details how to transfer music from your computer onto your Sansa.
So , -Plug it in! - plug it into the computer and wait until it comes up -Open your music software - Open your iTunes or Windows Media Center and access your music -Open the Sansa "Media" folder -Simply highlight your music and drag them into this folder and you should be able to access them!
If you are attempting to download directly from the internet onto your unit, you must first save them to a folder on your computer and then you can drag them onto your Sansa just like with music files.

If your music has DRM it willonly allow you to sync once. they want you to repurchase the music. Try syncing music that is DRM free. If the new file work that is your problem.

Do you have WinXP /Vista, etc? OS = Operating System :)

ok buddy...it might be problem with the storage.. try to format the player once.. now the player will be fresh... now download all the songs and try whether its working fine... if the problem continues try to contact the player manufacturer for replacement

I use Rhapsody with Vista. You need to go to Rhapsody's website (or Best Buy Digital Music Store, which runs the same software) and download the updated version, which will work just fine.

Purchased music from iTunes can be put on Sansa players as well when you set-up Rhapsody to manage your music. Have the program detect your music library and then all you have to do is drag and drop to your MP3 player.

Go to this site:

You actually don't need the software. Follow the below steps to get your music on it. You are better off with the software they include, it's kind of intrusive. Plug into USB Go to my computer Mp3 player shows up as removable disc usually drive F: double click drive F: to open it Click and drag or copy and paste your music into this drive and you are good to go Good Luck
