Agentry SAPUI5 OpenUI Container Demo - Access issues

Experts - I'm going through the Players demo in the EAM Mobile Apps SDK 2.1, and using the WPF client to test. When I click the Collection Extension link in the Players app, I get a script error "failed to load 'sap/ui/core/Core.js' from ../sapui5/resources/sap/ui/core/Core.js - Access is denied. "

I have given full permissions to the Assets folder and run the Agentry client as Admin so I feel this may not be the real issue. The directory structure for the file is clientdir/Assets/sapui5/resources/etc..... Any ideas?
