first, turn off your computer and plug in the USB connector. Then restart your pc, and turn of all programs that are runing in the background, especially your antivirus software. You may have to go into your control panel and click on game controllers and update or add a 2 axis 4 button controller. After this is added, go into Realflight and calibrate your controller. Hopefully, it will work without any problems after that. (cross your fingers and say a prayer though, just to be sure).
