Tartarus Pro issue

Hi. I am trying this game pad out, coming from a Logitech G-13.

I have 2 questions:

1. How do you back up (export) to the cloud? If I try to import it, there is nothing in there to choose from, in the cloud.

2. How can I re-name a keybind? For example, I don't want to see, just a letter R, I would like to name it, "Reload" is there a way to do this?

Thanks in advance!
