Hi,
I don't know if you solved your problem but I found a way to solve mine, so I share it.
I experienced the exact same issue: install went fine and all buttons worked. But not the DPad.
So if every button works, including the shoulder buttons, here is the solution that worked for me: click start to open the settings menu. You want to get to the controllers settings but cannot because of the DPad. Just use the shoulder button that makes the selection jump a few items lower in the list. Use it until you get all the way down to the last item. And then use the other shoulder button once to jump back up little. It should put the selection right on the controllers settings item! You can now click on the button that selects (B I think). And configure a new controller (thankfully it's the first item in the list).
And you can then map 'up, down, left, right' with the DPad directions. Done.
Worked for me where all the suggestions above failed.
