How to update the firmware of pymakr

[lodhi]

Hello Everyone,
I am new here and also working first time on hardware. I have pymaker expansion board v3.1 when I try to update the firmware of the board using Zadig every time It failed. I followed all the instructions which are given on documentation of pycom but still unable to find the solution. I am also attaching the screenshot of the error which I received while updating the firmware on Zadig
