Hello and sorry you're having problems. Where did you purchase this Fire TV stick from please? The reason I'm asking is that I have three of them right here, and if your Amazon username and password ***** not being accepted- then it sounds like your device was already registered to another user. Also the batteries not being good, also points to this unit being used, refurbished, etc. Let me know.
Bizarre. The Fire TV box is no longer made and the only one they sell now is called the Fire stick- and it plugs right into the HDMI port on the TV. So you're saying you have an external box, and not something that sticks right into the TV's HDMI port?
