I post a pic in a message below. It must show the complete screen you have to find to download the file. If a icon in the end in the right part of it where you can download it.
You may see a way to find it. It say you can't see the file but you can download it. Using the arrow icon next the register button.
Maybe you could use a computer to download it and transfer to your device. I am using a tablet here after all.
