Yes i did try. I have found the root of the problem. It is to do with Vista's default Music folder. I seem to have messed that folder up and deleted it or something, hence i could not save my iTunes stuff in there. I ended up creating a new user account on my laptop, and it has all the original default folders, so i tried running iTunes on that account. It works, but it's just troublesome i have to switch to that user account to upload music to my iPod.
So, i am wondering if there's any way to restore my default folders that come with Vista.? anyone know?
