mixed up files.

Hello again,
(Do users really use the standard "Hello" whenever they post, or just go straight to the question? Anyway, this question/s a toughy, especially because I'm not really sure how to ask it. Well here goes...Trying to print some selected music files from Audio Central is what started all this...It didn't give me a print option, so I went to the media player...couldn't print from here either, "all audio" or "my shared folder" as well. so, frustrated, I tried copy/paste, tried dragging from one to the other, and really made a mess of it all. Not knowing what I was doing, and trying to get ALL MY TRACKS in one big file, I managed to get one of the files messed up, I now have Duplicated all the tracks in this file, and they all show up again in this same file as SHORTCUTS! how, do I get out of this? In "all audio" it doesn't show all the songs in the computer, somehow I got them split up? I want them all in one place so I can make my playlists from there, but I'm sure that trying to make the playlists started all this, because I can't seem to get the hang of making playlists. To add to this mess, a lot of the tracks in Audio Central,(when I try to play them) a little window pops up and says ["Audio Central, cannot find missing file".????] but, in that same list of songs, the song right next to it will play??? What have I done??? Anyway thanks for the help in the print screen, it was so easy!
p.s. How would I get on the chat line? Do I need to get a pc microphone?
