When attempting to update your Circuit Mono Station you click 'Connect Circuit Mono Station' at the bottom left of the screen.
It should turn from orange to green and show 'Circuit Mono Station is connected'.
If connection fails please try then following.
- go to Device Manager (Make sure Mono Station is NOT connected)
- click View then Show Hidden Devices
- go to Sound, Video and Game controllers
- delete all the Circuit Mono Station and Mono Station Bootloader devices
After this re-connect your Circuit Mono Station and click the Connect button in Components. It should now turn green and show Circuit Mono Station is connected. You can now run the firmware updater.
