Lately, Windows Media Player (version 11) has been giving me problems. I can't create or delete playlists or songs. I found out that this version is embedded with vista, so i can't uninstall it or repair it. I create a playlist but it won't show up in the list of playlists, so each time i want to add a song, i have to go into the folder the playlist is located, play and add songs through other folders. Any suggestions as to why it's acting up?
