haha nevermind HBOgo. Since we know you are able to activate it then we know the verizon username and password is correct and that HBO recognizes it as legit. Why it keeps asking for it might be a glitch with HBOgo app or their server or it might have to do with the apple TV not saving your login info, so HBO keeps asking for it each time you go there. Kind of hard to nail down since it involves an Apple product, HBO, and Fios TV all working together. Not sure who is to blame at this point. I don't know if anyone else has had this problem with Apple TV's. Are you able to access HBO from your verizon set top box?
