Can't finish enrollment into the Creative Portal

Why can’t I continue enrollment?
I started the enrollment process yesterday and when I wanted to complete it today it shows me a “CONTINUE ENROLLMENT” button but when I click it nothing happens (it starts loading but stays on the same page). I tried: Logging out and back in, using different browsers, clearing my cache and restarting, clearing all cookies… but nothing works! Can someone help me please?
