FIRMWARE UPGRADE ERROR

your irivers firmare is lets just say  um broken and is unreadable
sorry but youll have to send it back to the factory

I got help from someone on this site that helped me fix my player. What you need to do (or what I did) is delete all of the RCA files from your computer completely. Then download the firmware upgrade from the RCA website (www.rcaaudiovideo.com) Once you finish that download, make sure that the player is not connected to your computer. Begin to press both the "Play" and the volume + buttons at the same time and then plug it into your computer. Then start the firmware updater at the same time; eventually, your computer will see that your player is there and that is basically all that I did.

# To install this firmware upgrade, do the following:

1. Download the MuVoV200_PCFW_LF_1_05_02.exe file into your local hard disk.
2. Connect your player to your computer.
3. Double-click the firmware upgrade file.
4. When prompted to set your player in Recovery mode, disconnect your player from your computer.
5. Press and hold the Play button while connecting your player to your computer's USB port.
6. Continue to hold the Play button for about ten seconds after connecting your player to your computer.
7. Release the Play button when the Find New Hardware dialog box appears on the computer screen.
8. Follow the instructions on the screen to install recovery drivers for your player.
9. Double-click the firmware upgrade file and follow the instructions on the screen.

Reformat and upgrade the firmware

REFORMAT FOR WINDOWS MEDIA PLAYER - Erases Everything: Connect your Sansa player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "Sansa 1GB" (wording may vary slightly), and then select "Format." - this should erase everything.
FIRMWARE UPGRADE - Erases Everything: Get the latest firmware upgrade from Sansa - it updates the firmware and erases every song in the player all at once. Note: this method doesn't work if already have the latest firmware. Go to this website and click "Firmware Updater" to find out: http://www.sandisk.com/Retail/DriverDownloads.aspx

Hi, you can try to upgrade the player's firmware, you can download it from the RCA Website (http://support.rcaaudiovideo.com/downloads.aspx?product=187), the firmware it's the second app listed.
If your computer doesn't recognize the player, you'll have to turn it off and keep "PLAY" pressed for 10 seconds while connecting it to the USB port, then update the firmware.

This is straight out of p. 67 of the user's manaul, available on iRiver website (it may not work if the computer does not recognize the device):

I had this same problem and almost threw out the Zen.

The trick to getting the Zen recognized by the firmware update software is to make sure you uninstall BOTH WMP11 as well as the WMP11 Runtime. Those two things are listed separately in Add/Remove programs.

BOTH must be uninstalled before the firmware updater will recognize your Zen.

Now I'm back to using my Zen. It's all good.

You need to update the firmware of your mp3 player, try to look for firmware upgrades for your specific brand or model...

maybe you need a firmware upgrade. Check your particular models brand and visit their site to get a firmware upgrade. Or you maybe just need to reformat it by plugging it to your computer and then reformat the device. You need to add some more details of your product to get the best response for your problem... have a Nice Day!
