Mission Planner 1.3.69 not working Pixhawk

I want to upload the firmware to my new Pixhawk from MRobotics, but I’m not having any luck. Mission Planner says "Failed to download new firmware: System.IO.IOException: The port ‘AUTO’ does not exist. etc etc

In QGC, it is saying: “Waiting for Vehicle Connection” and "Plug in your device via USB to start firmware upgrade.

I don’t see any COM Port choices in Mission Planner and I think this is why QGC isn’t picking up the controller, too.

I’d greatly appreciate any help on this since I’d love to get this controller running and up (strike that, reverse it). Tried looking at COM ports in Device Manager, they’re there but hidden and wondering if anyone has solved a similar problem.

But basically it seems you need to reinstall/update the drivers.
