i mostly use it as a media streamer using plex, i don't expect to get amazon instant video, but i can't even get past this screen.
thanks a ton!!
Did you try contacting Amazon support? They're usually very responsive.
Also, look up a way to remove the FireTV from your account so it can be reinitialized. It's probably confused because of the country change. You should find this from your Amazon account on the web.
