Hello, whenever I try to run any .NET application which uses Managed DirectX, I get the following exception:

System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E)
  Source="EmptyProject"
  StackTrace:
       bei EmptyProjectSample.EmptyProject..ctor(Framework f)
       bei EmptyProjectSample.EmptyProject.Main() in P:\Microsoft DirectX SDK (June 2007)\Samples\Managed\Direct3D\EmptyProject\EmptyProject.cs:Zeile 404.

It used to work yesterday... Uninstalling and re-installing the June 2007 SDK did not help. The assemblies are in C:\windows\Microsoft.NET\DirectX for Managed Code. However, the DirectX Control Panel says "Managed DirectX is not installed": Screenshot. Does anybody have an idea what could be wrong? Tubos
