Hi @stanman
Are you getting the Opps message when attempting to enter the six digit code from your television screen when going to the NowTV webpage by following the instructions on your television screen when attempting to setup & activate the Stick ?
You could try a different internet browser or another device such has a smartphone when trying to enter the code, but a couple of people have encountered this problem and NowTV are in the process of fixing it for the accounts that are effected.
I have sent a PM to a NowTV Staff Member to see if he can pick up your post from here or send you a Private Message.
