iTunes Get Artwork: "Artwork for [album name] cannot be found. You do not have permission to access the requested resource."
I just installed iTunes 10.5 (latest version as of 11 Jan 2012), onto a computer running Windows 7 Ultimate x64. I loaded my music library into it, it compiled the list and separated them by album. But even though I'd assigned most of the albums artwork through my Zune management software (a Microsoft product), almost none of them populated into iTunes. So I went through and started asking the software to try to find album artwork where possible.
I did this a few times album by album, then I decided to select multiple albums and see what happened. No problems. Then I selected all of the albums I had--about 600 in all--and asked it to get artwork. It seemed to process for a bit, then came back with the error, "Artwork for [album name] could not be located. You do not have permission to access the requested resource." I tried this on several individual albums, only to receive that same error.
The very first time I did it, I was told I needed an account with the iTunes store to make it work, so I signed in using an old Apple ID (the account had been inactive for so long it had been locked for security, I unlocked it and that seemed to be that). Then I did what I described above.
The weird thing--to me--is that I can still add artwork to the albums manually if I want to, from imagery stored locally on my own computer. The only thing it seems to have a problem with is when I ask it to go find artwork from the iTunes store.
Do I need to uninstall iTunes and then reinstall it? Did something go wrong with the process of authorizing the computer to work with the iTunes store? Do I need to de-authorize and then re-authorize the computer? Could this be something related to Windows permissions on the iTunes library?
