I recently put Nero 7 and Cheetah DVD burner on my system. But when I deleted them both, didn't like them, all my files in limewire changed to MPEG's. I want to return them back to media files. Right now I cannot listen or view any of my music or videos on windows media player b/c all the files are MPEGs and the music files ONLY can be played using the limewire media player. Does anyone know what I have to delete or do to change these back. Thanks.
