I've just set up my 2nd Roku on another TV. When I navigate to Netflix it asks me if I'm a current customer. I choose yes, a screen flashes for a nanosecond and then I get an "activation error" screen where I have the option to get another code or to go back. So I choose "get another code." It flashes on the first screen again (I can JUST make out that it is trying to generate an activation code), and then I get the "activation error" again. This is going on and on in a loop. Any suggestions?
