If all else fails, you may want to contact or email customer support. I had the same issue with the candi theme and support was able to email me the direct link and I was able to download and install. If you do, don;t forget to provide them your order number. Good Luck!! )
If you download a theme and it's listed under Options >Advanced Options >Applications, but not listed under Themes, it's for the wrong device or operating system(OS)
