Can't activate my free licence

I registered for a free licence and was issued an activation key. I have a problem activating it, however. The instructions say that I have to do the following:

  1. click on Help in the top menu
  2. Select “License”

 When I click on Help, there is no “licence” option? Please help!

That’s strange. This is what you should see:

I looked in the wrong place; thank you for your help!
