I was recently sent a gift of some Itunes music. I have the latest version of Itunes installed on my computer, a Dell Inspiron 1525 with Windows Vista Home Premium. When I try to obtain the Itunes music I get a message that says "The folder "itunes" is on a locked disc or you do not have write permissions for this folder."

I have gone to the permission section for Itunes and selected"write".  Please advise as to how I should proceed.

Thank you - David
