FS NAVIGATOR.

Hi Folks.
I have managed to get hold of FS Navigator which is asking me to provide registration details. I contacted the designer who gave me the registration details explaining that they would allow operation of FSN.
I have looked right through the programme. and on the internet, and can't find anywhere to enter the reg details? There is usually a page or a section for this - but nothing?

Can anybody remember how they did this, and where the registration section is so that I can get FSN working?

Here's hoping.
