ive been using limewire for a little while but now when i search for songs most of the results appear as windows media player files and hardly any as i tunes files where this used to be the total opposite i dont think ive changed any settings i tried downloading a song and cant play with media player or itunes what have i done. Thanks Jim

Did you have iTunes set as your default player before? You might have to check & see if it's still set as the default.
Setting default player

If you don't want wma files, you can filter them out of the search results by adding .wma to the keyword filter (tools > options > filters > keywords).
