Been trying to activate the Web-Filter License on my DrayTek Vigor 3910. I get to https://myvigor.draytek.com/products/register after being redirected from my router but after filling out the name and pressing submit I get a 404 error as shown in the image below. Any help would be appreicated.

Strange - I've got a similar issue trying to add my Draytek 3910 to myvigor. I get redirected to screen https://myvigor.draytek.com/products/register/XX-XX-XX-XX-XX-XX/confirm (where XX-XX is the MAC address of the Router) and after 30 seconds or so it times out with the error 'Adding Device Failed'

I've raised a ticket - i''ll update here if I get a response
