Purchased an IBU2 after being convinced from the website its a 'plug and play' for Taigen tanks

Anyway managed to get it wired in easy enough, although its just a little too big to fit in the chassis alongside the battery. Calibration was a nightmare but thats more down to my cheap 2.4ghz transmitter i believe.
Now comes where im struggling, ive got my SD card into the laptop and nowhere did i read beforehand you need to be a computer programmer to set this up? Myself and my wife have both studied the instructions in detail and cannot make head nor tail of what we're supposed to do?

Any help be grateful, im not completely computer illiterate but at the same time i dont hack computers for a living either.
