Game not Working in Windows 8 but works in Windows 8.1

I am working for Windows Store App. I have a problem when i build by selecting Windows 8.0 platform. When i build my game for Windows 8.1 it works correctly, but for 8.0 it not works correctly. When my game-play scene is started then my application crashes.

after i click break then it shows me a page not referring any script. My setup is Windows 8.1 and Visual Studio 2012 for Windows 8 and Visual Studio 2013 for Windows 8.1

Please help me to remove this bug as Games for windows Store 8.0 will also be able to windows run on Windows Store 8.1. Help i found yet on Google still cant solve my issue

Thanks, Asfand
