not sure i understand. if you've successfully gotten to step 16, then you've successfully entered all of your info. hit the home button on your fire tv stick remote and then go down to settings and then over to manage all installed applications. now go down until you see STB Emulator and "force stop" the app and then launch it. tell me what you get.
update: i've duplicated your issue and it appears that you haven't entered settings by using the bluetooth mouse or mouse emulator. do you have a bluetooth device capable of emulating a mouse? if not, you will need to obtain one and begin at step 5.
