Decklink HD Extreme 3D + Drivers not working

I'm trying to work with Resolve, but the output screen from my Decklink HD Extreme 3D is just black. I've updated the Desktop video to the latest drivers, but when trying to go into the settings in the Windows 7 control panel it just says that I do not have any desktop video devices.

Has Black Magic stopped supporting the card? If so, how do I get output video from Resolve 14? I'm on a deadline here and this is just frustrating.

Had the same issue. Go back to the Decklink driver that works for you, install the latest 15 and you should be good.
