Just got our Softplan+ 2016 introduction Package.
Using our Primary Key number, we get the message "You have to be a Softplan+ Subscriber to Download"
Using one of the Secondary Keys we get "Note this is NOT the new 2016! You will be notified when 2016 becomes available to you".
Luckily, using my Secondary key, we were able to start the Download.
Not sure why it doesn't work with our Primary key, but does with a Secondary.
Good job we had a few options.
