Unhappy ADB problem (im a noob)

Hey, im trying to root my kindle. Im following android cowboys method and trying to install the ADB drivers. I'm sure im doing everything right but when i plug in my kindle and go to device manage, it doesnt come up with the yellow triangle. It just says kindle. Am i doing something wrong? I have restarted the kindle and laptop and also uninstalled the kindle drivers and ADB drivers but this still has done nothing. When i uninstall the kindle drivers and i plug the kindle back in, i do actually see the yellow triangle and i think it says android but then it reinstalls the drivers by itself and goes back to kindle... :/ Anyone help please?
