Last nigh I started not being able to add TP on my Viewsat Ultra. When I press F1 the screen flashes but the new entry never comes up. I have unplugged the unit and hard powered it. I would prefer not to restore factory defaults, because it would take a week to re-add all the Sat information. Any one ever had this issue and knows how to fix. Everything else works fine. I can edit TP and delete just not add. Original firmware. Thanks for the feedback
