Hi Le Ann,
· Are you referring to Windows Media Player?
· Do you get any error message?
· Has it ever worked?
Follow these steps:
a) Plug the SD card into the memory card slot on the computer. If the computer does not have a memory card slot, connect an SD card reader to the computer, then plug the SD card into the card slot on the reader.
b) Click the Windows "Start" button and click "Windows Media Player" to launch the media player. Windows Media Player will recognize the SD card as a portable hard disk and display it in the left pane.
c) Click the "Library" tab. You should see a list of songs in the library. Click the "Sync" tab on the top to show the "Sync List" in the far right pane. Drag songs from the library to the "Sync List." Drag the songs in the "Sync List" up or down to set the playback order.
d) Click the "Start Sync" button when you are satisfied with the list. Windows Media Player uploads the music to the SD card.
e) Close Windows Media Player when you finish. Click the "Safely remove hardware" icon on the system tray next to the clock.
