Hi Tony,
Are you using IE?
Viewing designs currently works only in browsers that support WebGL: Chrome, Firefox, Safari. IE 11 support is on the roadmap.
Some users on IE are seeing a "No access error" instead of a more helpful message that lists supported browsers. The team is investigating this.
Until then, do try on one of the supported browser and let us know any other feedback you may have.
Thanks for your patience.
Rajiv

Personally i'm using Google Chrome and havent experienced any issues like yourself yet.
