DirectX Problem?

[NoNameNoNumber]

Trying to run Rivals of Aether... I keep getting this error code and a crash though...

FATAL ERROR in Vertex Shader compilation
ShaderName: shColorReplaceBlendExt

D3DXCompile failed - result

I've run dxdiag to confirm I'm running dx11... Not really sure what to do from here?

Any ideas?

I looked to disable shaders but I couldn't see an option for it... Left the PC upgrading to Windows 10 Pro today so will try when I get home tonight...

Worked a treat, thanks
