Trouble with music files
 

First, I'm pretty much a novice at this,so I'm gonna need answers in simple terms and instructions! I've downloaded music off limewire..the frist time I was able to drag the files into the CD creator and burn my CD. The next time I downloaded music...on limewire, it said the download was complete..the file saved... But when I went to my CD creator it showed that the music file was there but the size said 0MB and was an invalid music file! Any ideas? Please help! And, thank you to anyone who answers!!!!
