This is a known issue when moving source files around to different folders without uninstalling the Metro Style App.  The good news is the fix is simple!

Uninstall the application via it’s Start Screen Live Tile and then re-deploy it in Visual Studio 11.

I have this happen to me frequently due to having different machines I present on and moving source code around between them.  I figured I would share the solution in case you come across the same issue.
