I downloaded the recent update to 18.1.0 of the software and when I ran the test, it said I needed to update my firmware. I attempted to update firmware but, for some reason, the firmware update would not come through. I even left it overnight and noticed to progress in the update. My v2 now has a flashing red light on it instead. Any help would be greatly appreciated. I'm running windows 10, by the way, if that matters.
