Wont copy songs to mp3 player because of write... i have many songs that I have either downloaded

Question

i have many songs that I have either downloaded on my computer through limewire or loaded from actual cd's, and created one playlist that i have attempted to load onto my gpx MW238P player and no matter which method I use to load them onto my mp3 player, a message comes up saying it cannot load them because the files are write protected. I dont understand it, i can copy all the songs onto a cd, but not into the mp3 player? Please help! Brenda
