They have real player icons. I deleted the real player applications a couple of years ago. But I'm thinking that I should delete any remaining real files (plug-ins, extensions etc). iTunes is able to convert and play the 2 new files. Quicktime was then able to open the 2 mp3 files from my iTunes library. It's just that all my previous downloads were automatically QT and I was able to preview and launch in LimeWire. Now the default application in Limewire is RP and I can't launch or preview the files. At least I can save and play them in iTunes. It's wierd - that just updating my QT software would change things in Limewire. Thanks for your advice.
