Setting up Test Driven Development with Visual Studio 2008 Beta 2

Here I am, setting up Setting up Test Driven Development with Visual Studio 2008 Beta 2:

• Installed NUnit : NUnit-2.4.3-net-2.0.msi (really need to install first)
  
• The I tried to install TestDriven : TestDriven.NET-2.0.1714_Personal.exe. Well it failed. So I tried TestDriven.NET-2.8.2130_Personal.exe. And it worked. At least right click shows the proper menus. When I right click a test case and try to run test though, I got "Couldn't connect to test runner process". Still I can just right click -> [Test with ... ] -> [InProc]
