Had to download it a few times before they were there. Not sure why. But now I have them all :)

I had the same problem. The default windows zip extracter fails on contained files whose total file path is too long. One fix is to rename the .zip file from "Hana Carake - Fantasy Interior.zip" to something short like "H.zip", then extract and it works.
(Alternately, just hit "skip" when extracting all the too-long files, they seem to be mostly cache files that don't need to be in the folder anyway.)
