Can't put new music on player

Hi Raxter. As long as you can save files to the player (seems like pictures and video work just fine, right?), then the player is not experiencing any corruption or firmware issues. Perhaps the issue lies with the songs you're synchronizing to the player. There are several reasons why you would encounter errors when synchronizing songs to the player: (1) File type is not supported by the player -- MP3 (with a bit rate of 128 Kbps) and WMA files (with a bit rate of 64 Kbps) are the only supported music file type. MP3 music normally converted via iTunes is not guaranteed to work on this player. (2) Windows Media Player 10 is the only tested Microsoft player version to work on this player (trust me, I've had my bouts with other Windows Media Player versions lol.) Version 11 works, but I have had issues with the player experiencing errors when syncing songs. (3) If the songs are licensed or subscription, it's probably best that you use the subscription provider's media software to "synchronize" the songs into the player (like Rhapsody or Napster player. Music Match often causes the player to "restart" -- I have no idea why, better call them). Some music providers are unable to actually support the player (or recognize it for that matter). It would be best if you contacted the subscription provider to give you instructions on how to synchronize the songs from their website. If your songs are non-licensed songs (like songs from ripped audio CDs, Limewire, etc), then it's best to switch the player's mode to MSC and transfer the songs by simply "Dragging and Dropping" or "Copy/pasting" the songs to your player. To switch your player's mode to MSC, navigate the Menu as follows: Menu >> Settings >> USB Mode I hope that would resolve the problem you're encountering with your player. There is another way to reset your player, but I'm hoping these options would actually let you transfer files successfully. Let me know the results.
