The file is probably corrupted. What kind of message are you getting? What it says?
You can try to download the game again and install it to see if that works.
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.

I think people just find confuse to download using Dropbox.
1st time I had difficult to find where to download it.
I had to choose that I didn't want use the dropbox app.
So later it show a screen where give many options. To use the account, register, download to your account or direct link to download.
Since I am not used with Dropbox, I always click in the wrong options by accident at 1st. Hahah
Later I go to the right way page to page until find the download icon.
Of not that... I have not idea.
Must be this page.
