i also havethis problem and it says:
Failed creating D3D device of at least version 10.0 on adapter "Mobile Intel(R) 4 Series Express Chipset Family" with driver "Unknown". Error is DXG1_ERROR_UNSUPPORTED ("Unsupported.").
This is typically caused by not having the minimum required DirectX support in the GPU.
For NVIDIA GPUs, DirectX 10.0 support is required.
for AMD and CPUs from other vendors, DirectX 10.1 support is required.
bye.
