Hi I have 2nd gen Router and Dish but im having problems signing up for a new account. I go through all the screens ok until it comes to paying. The web site says "Further Authentication Required" then just times out. I have spoken to my Bank and it appears the web site has a problem with "SCA Security" and I need to speak to the Vendor which is not possible as no phone number available. Help Needed Mick
