Unable to playback music
 

After reloading program, I am unable to listen to (launch) any music while downloading nor after completion from library

Don't hold me to this but I think your problem may be that you don't have a Music Player. You might want to check if you do or not. If you don't, you can download these practically anywhere. Just search for one using Google or Ask Jeeves (www.Google.com or www.AskJeeves.com). When you search use terms like "where can I download a Music Player" or "sites that have downloadable Music Players".
