So I was merrily going through my collection adding album art through the Tag Sources > Cover Art > Amazon.com function, then all of a sudden it stopped working. It will connect and find the album art, but when it goes to tag it is successful in "0 of 0 files" (happens if I have 1 or many selected).
This problem is occurring for all albums. If I manually add art from my hard drive, it will save the tag.
Any help illuminating the problem would be appreciated.
