My MP3 or MP4 player does not let me load any music onto the unit?

Please do not be alarmed there is nothing wrong with the MP3/MP4 player you purchased. When purchasing music online, many of the songs may require DRM compatibility. In DRM mode your unit is restricted to only work through Windows Media Player, and will only allow you to load music in folders. These folders must be no larger than 127 files. In order to switch out of DRM mode so that you are not restricted you will need to change the mode. This device has two different modes. One mode is the USB Disk mode, which is normally used to transfer data to your device that does not require DRM compatibility. In this mode, when the unit is connected to the computer, the unit will show up in ?My Computer? as a designated drive and not as a separate ?Other Device?. In this mode, you can play all non-DRM music and/or video. This unit also has a Media Disk mode. The Media Disk mode allows DRM compatible music to play on your unit. When connected to a computer, the device will not show up on ?My Computer? as a drive. Normally, this device will show up in ?Other Devices.? To change the mode of your unit from the DRM mode to the USB mode you will need to: On the main menu screen, select the ?System? tab on the MP4 Menu. Then scroll and choose ?Online Device.? Once you have opened this icon, there will be two options: Media Device or USB Disk. In order to allow all music to play on the unit and not restrict the files make sure it is in USB Mode. Use the next/prev buttons to scroll down the list and highlight the version you would like (USB Device). Then you can press and hold menu to select and exit the screen.
