Directx 11 problem

[Sansus]

Hi im new here. Im using dolphin rev.6761 and i get error "Failed to initialize Direct3D. Make sure your video card supports at least D3D 10.0" when i try to use direct3d11 plugin. And im 100% sure my NVIDIA GeForce GTX 275 can handle directx 10. So i dont get why i get this error. The game i want to play is One Piece : Unlimited Adventure where i get white fog and i have red that playing on direct3d11 plugin removes this problem. Info in dxdiag says im using DirectX 11. So im realy confused. Any idea how to fix this problem?
