I cant put songs on it with windows media player

thats because the itunes files are formated to .acc and not mp3 and may be right protected you can try and convert them to .mp3 and they might work try it and if not then there right protected

Ilo player must be synchronized, coping and pasting files is not enough:

1. Start Windows Media Player and select following menus: "File.", then choose "Add to Library." then the "Add" button. Then, look for the folder where your keep the mp3s to upload.
   
2. Plug the Ilo MP3 player into USB.
   
3. Click the "Sync" tab that you find at the top of Windows Media Player . You will find the Ilo MP3 player on the right side of Windows Media Player. If Ilo is not ther, then right-click on Sync tab and click "Refresh Devices."
   
4. Click "Library" then "Songs." on Windows Media Player . Highlight the son songs, and choose "Add to Sync List."
   
5. Click "Start Sync" button that will appear at the bottom right corner of Windows Media Player. The songs will then be uploaded to the Ilo MP3 player.
   

You can't use Limewire directly to transfer songs to the Nextar. You will need to transfer the songs to the Nextar using Windows Media Player. Limewire puts the songs in a folder called "Limewire Downloads" usually. You will need to open Windows Media Player, run the mouse over the "Library" tab, and select "Add to Library." Once the window pops up you will need to add the folder called "Limewire Downloads" - it may take several minutes, but Windows Media Player is going to add all of those Limewire downloads to its own library. Then, you can use Windows Media Player to transfer the songs to the Nextar.

That's a DRM error and should be solved by the FairUse4WM which you can download for free from the following link.:

This will rip the DRM off the tracks and you should be able to sync it or listen to it without a problem.

Sounds like the files are DRM copy protected.

You can check for protected tracks.

• In Windows Explorer, go to the folder where the tracks are stored on your PC.
• Click on View -----> Details
• Right click on the header bar in the right hand window and select protected. (If protected is not listed click on More)
• Tracks will be listed with No or Yes under "protected". Check your non-playing tracks are listed as No, under "protected".

The HDD1830 is not compatible with protected files, although your PC will play them ok.

well songs u dl may be protected ok or if uuse windows player 11 to trafer on hd set the settings at mp3 128 bit rate in options then trafer at that not wma those will be protected in players ok thx nick

Here's how you get it
you may have to open Windows Media Player but maybe not
a screen will come saying for you to choose either NO leave all the media on the device... or YES delete all media.
click YES but MAKE SURE you have the HOLD button on OFF. if you dont... it will not work
after it completes the task click FINISH

i tried for hours trying to figure it out and that made it work like a charm! =]
