Platform::COMException ^ at memory location 0x0669FAB0. HRESULT:0x80070490 Element not found.

Touchscreen - Start -> VS 2013 Popup

My build with Unity 4.6.1p2 fails (as did 4.6.1f1) with the error below when I save the project and run with Visual Studio Ultimate 2013.

Build Settings:

Windows Store
XAML C# Solution
Universal 8.1
Build & Run on Local Machine & Windows Phone
Debugging
Unity C# Project
Development Build

I save this & then run the 'Local Machine' to test and get the below error. I also have attached a log of debugging information...
