weird situation, anybody really know their stuff?

[BradFazner]

hey guys, bought firetv a while ago in usa, worked perfectly, was a prime member so it came all setup for me. moved to canada, screen popped up:enter your existing PIN set for amazon instant video. i try what i think it is, like 00000 or 12345, doesn't work AND the error is A connection to the internet could not be established. Please try again later. got a new modem/router when i got internet here in canada, then switched to my original router from usa, still has the same problem.

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!!
