I have been using the Xamarin.iOS licence on Xamarin Studio for Mac. It has expired today, I noticed as I cant build my solution. It comes up with a window with two options. 1) Purchase a licence 2) Use the starter edition. I am currently on the business plan so was expecting it to activate automatically. The Manage subscription buton on the website takes me to a page where it shows the Mac on which I have it installed and in 'licence' drop down menu there are two options (Deactivate and Download).
What steps do I need to take to activate my licence?
