Want to edit my live website but have lost the dashboard

I’m not sure how to explain this. My website was displayed on a free version of WordPress. I then purchased Canvas from Woothemes and uploaded it. It automatically updated the free version and converted it into Canvas. It comes up when I type the address into the browser. https://www.whoareyounow.co.uk. How do I access the dashboard, so I can edit it. I can’t find it anywhere and don’t know where to start looking. Please help!
