Doorbell video pro

Just fed up of this For more than 3 hours I'm trying to make my doorbell video pro to work. \- Connects \- instantly shows this message (updating software)\- after 5 minutes waiting "I can hear welcome to ring the world most video door bell"... \- start same process over and over again and since 21:00 we are fighting.... I can't make this to work. \\UNBELIEVABLE total disappointment and dissatisfaction. Last month same big problem 3 days calling to try to find the solution.
