I had an older version of limewire runnig on a Mac using iTunes as my MP3 player. When the downloads were complete, I only had to click on them and the opend my itunes software and played. Now, I am running LimeWire 2.5.5

When the downloads are complete, they are all showing that they are Real Audio files not MP3's and I have to convert each one before I can play it on my MP3 player. This never happened before.
