Cannot connect to naza software via micro usb

Hi I recently tried to connect to the naza 2.20 assistant software on my phantom 1. I am using windows 10 and to install and it won't read the Phantom. I hear the connection of the usb and the color blink on phantom but will not show the information when connected to the naza software. I uninstalled the driver and software and also tried older naza software. I want to calibrate the Phantom. I have the transmitter on and battery plugged in when running software. Can you please help. Thank you
