mp3 player

I recently purchased a mp3 player.  It plugs directly into the usb
port on the computer.  The player does not recognize  mp3 files that I
load into the directory.  It recognizes all the preloaded mp3 files
but does not even list the mp3 files that I load.   I tried several
different mp3 files.   I was able to list the files in the file
manager but the mp3 player would not recognize them.  I even tried to
load the files using Windows XP, but that did not work.  I would
appreciate any suggestions.  I had a response from the site where I
purchase the player but have not yet received thier technical support
help.
