I struggle, so please bear with me on my (probably awful explanation of where I am).

1) Paid donation. Got an order number.
2) using Amazon Fire Stick 4K newest version
3) Downloaded STB Pro Emulator onto the Fire Stick
4) Entering Portal info ok
5) Enterted MAC address ok from the MAC address generated on the Rocket page generator
6) STB Emu is on home screen of Fire Stick. I click, it says "portal loading" and then closes straight away. It seems only time I can get to stay open is off of fresh install after I uninstalled.

Thats where I have got to.
Appreciate any help.
