This sounds a bit strange. You're saying that WMP won't play or burn any MP3 files. I know that WMP has problems with some MP3 files but far from all.

You could try searching the web for a codec pack, but you should try first to see if the files are playable. Try downloading this player and see if it works first

www.videolan.org

BTW does the player in Limewire play the files ?

There are free converters out there but why take a file that probably allready has a little loss in quality and make it into e.g. .wma and have more loss in quality. If you choose to do that please do not share the converted files
