Hi, I have been going through the great tutorials at "https://channel9.msdn.com/Series/Introduction-to-WebGL-3D-with-HTML5-and-Babylonjs/" and am trying to run the HTML pages in either Chrome or IE. However, the pages never complete their loading. I am in Chapter 5 of the training, but also checked Chapter 6-8 also. Hitting F12 in IE I was able to see that an error message is being hit in the Babylon.js code. I have attached a screen shot. As you can see it is the manifest file that seems to be having the problem. Maybe the way the default security rights when it is created on the server? If you could fix it or tell me how to work around it that would be great. I am new to java scripting and web development. [NOTE: The folder contents do work in the sandbox, so I am able to see their work. It is just that the supplied HTML pages do not work.] Thanks.
