No Sound-have Player?!?!
 

Have 2 players (WindowsMedia, and Musicmatch). Not sure which if any are set as default. I downloaded a new player a while back and it set itself as the default.. I erased it and cant seem to make everything go back. SO my limewire files remain in silence awaiting your knowledge.

Running the installation for Music Match again will reinstall it and set MusicMatch as the default for playing MP3s. Just make sure not to uncheck the file type option during installation. :-)

Shift + Right click on a file of the type you want to play. (i.e. mp3, mpeg, wav, etc.) Click Open With... Check the box under the list, and find mmj in the list. Double Click it. You should be done and opening fine.
