Trying to begin a Trial

Decided to have a look at Squarespace as a possible option / alternative for Wix or Shopify. 

I simple cannot get the trial edit to start. 

Using Mac, Chrome, Safari ..all up-to-date.  Tried clearing cache, extensions and confirmed that Java Script was running.
I signed in using my Apple log on, all good. 

Followed the steps to choose a site template. 

Nothing, Nada, Zilch... I simply cannot progress past the selection of a template. 

Can anyone help? I cannot think of any other reasons why both Safari and Chrome refuse to let me in.
