Managed DirectX Documentation

Question

hi, i downloaded C# SDK for DirectX9.0 b and then few days back installed it. The readme file says that documentation for managed DirectX will directly appear in 'Contents' of Visual Studio .NET Help. It appears but when i try to see the help for particular topic it gives me blank page (like we get in IE when wrong URL is typed) on right side of Documentation Viewer! What must be the prob? i installed SDK correctly. Help for DirectX using C++ is available without any prob.
