hmmm well first i'd say you should get some better software, i have never heard of that kind.
I don't have nero on my computer anymore, so maybe someone else can send you the program.
Not sure what the problem with the cd is, it could be from a few different things. You'll probably have to toss it though, since if you tried to burn and it didn't work, it's as good as garbage.
When you burn a cd, it's a good idea to close any programs and not touch the computer. Most burners are fickle, it doesn't take a lot to F(*& up.
If you're looking for a better program to d/l mp3s, i'd recommend wimmx at
www.winmx.com
very easy to use, similar to napster.
