I have downloaded a number of songs and can play them in Limewire. All I want to do is burn a CD. When I click the burn CD button, it tells me that I need to install Musicmatch Jukebox. I did that. Will not burn CD. I purchased their Jukebox Plus ($19.95). Still can't burn a CD? Any hints? I'm on an IMac - 9.1 MacOS.
