Halo Custom Edition Manual Update

[M.A.T.T.]

does anyone know where i can get a update for this becaus everytime i try and play it i get a direct3d accleration error but i followed the support and it says about turning it on and when i look mine is already turned on and i have halo combat evolved and i updated that manually and it worked so i thought i might for halo custom edition

Thanks
