There might have come some basic midi-player with your sound card, by the way.
Hope this helps,
I am very new to computers and downloaded some music into the My Music folder so that I could copy it onto CD. The files are all midi and don't show up in any of my players. I have Realplayer, Musicmatch and windows media player. If I go directly into My Music the folders are all there but I can't do anything with them. I'm about to have a very quiet nervous breakdown, so could someone please help me without assuming I know what I'm doing!!!!!!! My operating systen is Windows ME
