It worked fine until I deleted the music on it.

refresh as much as you can. it doesn't readily delete or refresh sometimes.. you have to try it until you delete the file..

Try using Windows Explorer or similar utility.

In order to sync the files with media player the device must be in MTP mode MSC mode is used for drag/drop file updating. try setting MTP and then sync it or just open the drive file in my computer in either mode to update the file list.

a good place to go is friends21.com and choose a song to download, click download,then open up windows media player then click synchronize.

haha your welcome. good luck with your mp3 player in the future!

WMP doesn't recognize the players video file system, or your computer does not have the right codecs for WMP to recognize that file type

Delete from windows explorer instead - but be careful to only delete the videos, and not the system files/folders that control video for this player

Make sure the lock is not engaged. If it is not, then you have a Corrupt DB - double check RCA's website to make sure you have the latest firmware.

Turn off the automatic sync option - change it to manual sync, and then you should be good to go. Change to manual sync first, and then reformat.

windows media dont surrport mp3 u cant play mp3s but thats it. when u plug in the usb from ur mp3 player it should pop up new hardware found in the right bottom corner double click on that i should open up the mp3 folder after tat just click and drag the music u want in to that folder and ur on your way.

If your device is getting too close to its capacity, it will effect the menu on the device. You need at least 6-10MB of free space for the "music database". If thats not it, one or more of your files may be corrupt. To resolve this, you should format the device to delete all the music, then transfer it back to the player. To format, right click on the device under My Computer and select format. Please add to the question if that didnt work. Best of Luck.
