I have just started playing around with the Office 365 Napa development tools and was working on the tutorial for building an Excel Content App - http://msdn.microsoft.com/en-us/library/jj220065.aspx. The problem is that when I run the project it gives me an "app error" when the excel page is displayed. Now, I looked to see if all the files loaded and it seems that the office.js file is not found on the appsformicrosoft.com site. That seemed odd to me since I know others are developing apps this way and if the site was down there would be a firestorm. For now I am going to assume something is not setup correctly for me. So I am looking to see if anyone else has run into this issue and been able to resolve it. Any help is appreciated.
