Minecraft: Windows 10 Edition keeps showing the "Your device is no longer supported message", even though my Graphics card can indeed support Minecraft. 

The help states that my graphics card (which is an NVIDIA Geforce 8400GS) must be able to support DirectX versions 11 or higher. My graphics card has DirectX 12 on it.  

Is this some kind of visual glitch, or does my computer need to be updated in some way?

Thank you - Bill
