Emule/nero7 problem!

Hi everyone!!

I m new to all this so excuse me for being really thick!!! My user name says it all really.
Right here goes… I have emule on my computer (Still using XP!!) I have downloaded CD’s (shared files) to emule. I have installed Nero 7 (from a friend). I can play the audio files through Nero 7 but cannot seem to transfer the files from anywhere on my computer to burn to disk via nero 7. I have tried various different things and end up with a blank disc that can’t be reused!!! HELP!!!
Does anyone know what I need to do!!! Thanks xx:)
