Mp3 player problems

My Coby mp3 player, after about three weeks starting giving me not authorized messages on 96/100 of my loading songs. It will not let me listen to them. It doesn't give a reason why either. I haven't erased the memory yet because it wasn't full and I didn't think that I should have to reload all over again. I upload from Napster. I am a memeber. Is it a programed "time out"? I hope not, I paid for the songs. Thank you for your help.

SOURCE: What does Error 4 mean?

Take your sales receipt and player back for a refund. These players have so many glitches,hiccups,and charging problems that they should be pulled off the shelves. If the player performed as well as it looks then it'd be a nice gadget but this is unfortunately not the case...

SOURCE: COBY MP3 PLAYER MODEL MP610-2G "file sys err"

Go to the Coby website, look for your model player.On the that page there is an option to download latest firmware and the video converter.Download the zip file for the firmware.PLEASE NOTE...when you unzip the file please read the pdf file for instuction before you try to click the actual firmware file.One important reason is because using the firmware update restores your player to manufactures default and deletes all files presently on it....So my advice back up your files and read the instructions carefully.This fireware update is specifically to fix that sys err problem.

I hope it all works out

here is the link to the page

We do not know how many songs the player holds?

The number of songs will depend on the size of your MP3 player and it will also depend on how big the songs are.

Usually, the sizes of the songs starts at 3.4MB, 4.5MB, 5MB and higher. If you're going to load songs that has 5MB size, and the player is 512MB, it means that you could load up to 100 or 102 songs.

But if the songs are bigger than 5MB, then you could probably load for less than 100 songs.

Thank you and good luck!

make sure what your putting on is MP3 or unprotected WMA files. If the light is blinking, then it means its playing the song, if you hear nothing, the audio is not in the correct format.

i had the same problem, but after connecting it to my pc, via usb and looking in my computer under removable storage to open up the files in the player and make sure they were there, the player starting to work again after removing from my pc, worth giving it a try, unless you save all the mp3's to your pc then do a factory reset, within the player menu.
