I am having trouble with my MP3 player. I just got it and now that I am using it, I have run into a major problem. I do not know how to make a selection on it. I tried pressing the play button but nothing happened. It has like music, recording, replay, brochure ( =i think), and settings. Those are the selections. I, of course, want music, bt I can't get there!!!! Can somebdoy please help me?
