My Craig MP4 Player Will Not Download Songs

Question

Hello,
I seem to have a problem with my Craig MP4 Player.Whenever I try to download songs onto it,there is always a pop-up that says"please insert disc".But the problem is that,the disc for downloading will not fit into my computer drive.Is there a possible way that i could download music on to it without having to use the disc for it??Please give me back a solution for this problem.

Thank You Very Much And Have A Good Day.
