Stuck at the Quick Tour with Upfront Builder

Hi having my first play with the builder plugin & I can't get past the quick tour screen, the next button nor anything else is clickable. Tried in both Chrome & Firefox, upgraded WP to latest version 4.7.1, uninstalled & re-installed plugin, theme etc, no other plugins installed. How do I get past or deactive the quick tour so I can try out the builder? Thanks Kim
