I've put the Vienna Ensemble Pro 6 Demo in my basket, however once I get to the order summary stage, when i select the "I have read and agree to the * terms of service" button and click "place your order", the "terms of service" button gets immediately deselected and I get a red "Please agree to our Terms" error. I select it again, place the order, and back again to being deselected and the red error.
I've tried on Safari, Firefox and Chrome, and it's still impossible to get the Terms of Service button selected...
I'm on Mac sierra 10.12.6
