If you get the message "Link Party Not Found":

1. Refresh the page by holding down Shift on a PC or Command + R on Mac (check out this post as well: http://www.wikihow.com/Clear-Your-Browser's-Cache )

2. Try using another browser or an incognito window

If that does not work either:

1. Let us know the version of the browser and the OS you are using.
2. Send us a screenshot of the "console" tab of the development console of the browser (it comes up with F12).
