New to Cesium, can't load hello world

I’m a brand new user. I’m using IIS as my web server. I’m running on port 80. I’m able to open Cesium Sandcastle, but I get the following message, and I can’t load the blue world. Please help.

Error loading
Make sure Cesium is built, see the Contributor’s Guide for details

Its working now. I removed IIS and remade the site.
