Normally, whenever I right click a mp3[or any file for that matter], then click "properties", then click the "summary tab", then finally I click the "advanced>>" button, I am entitled to edit a multitude of things on that mp3. Now, for some reason I can only edit three things. I've uploaded a picture of what it looks like when I try to edit my music files. I also added the picture as an attachment in case the host site goes down.
Also my computer is working just fine aside from this little problem. Please !
