converting audio files from Limewire
 

I have only been using limewire for a couple of days now. I have been trying to download mp3s, convert them to .wavs and burn CDs. However, everytime I drop a file into one of my converters (Macast & Mpegger Drop Decoder) an error occurs with reading the file. I have converted many other files from other sources and the converters work fine. There are only errors with the file I download through Limewire. Any possible explanations or solutions would be appreciated.
