Well now that you made that "joke" and left nothing I guess you dont have an answer....
Sooo I will try again and hopefully someone with knowledge will answer

Does anyone know what "media usage rights acquisition" is, is it a program that is part of the downloading music on Limewire????
I hadthe same thing happen when I was using itunes,although there was no
"Media usage rights" to download..
I tried 4 or 5 different "sources" and kept getting the same thing..

Again, if there is anyone knowledgeable,I appreciate your help
