Can't start the campaign?

[Project Altaris]

Hi everyone! New to the forums!

Whenever I start it I get told there is an error bc of no key being entered.

What I cannot work out is where to enter my key?!

Where do I need to enter the key so that I can actually use the software?

I mean I've got one.....
