Anyone able to get My Backup Pro working?

[MRW1215]

I managed to sideload it onto the Kindle Fire (not rooted), as I was hoping to use it to transfer over my save data from the games on my phone to the versions I downloaded on the Kindle, but it won't "restore" anything. It acts like it's restoring it, but then when it goes to the summary of items restored, it's just a blank list.
