Computer not recognizing Telemetry? Or Mission planner?

Hi all. I’m using Mission Planner, and Pixhawk 4, and this telemetry module. I’m trying to use these instructions to connect, and I also tried this video but neither is working. My computer is failing to recognize any of my COM Ports so I try running Auto with the 57,600 Baud rate and it just times out. Anyone have any idea how I can fix this?


Un-unstall mission planner. Reboot and install the latest mission planner.
