Microsoft.VisualStudio.QualityTools.LoadTest could not be found


Hi Team,
i should do some tests with the Performance Toolkit but i have some problems.
In the instructions-document is described to run the web test "CreateNewNoteForAccount" but as you can see in the attached file there is no such test.
If i try to open the file "OrderedTest1.orderedtest" i get an error that the file "OrderedTest1.orderedtest" could not be read and that it does not indicate the expected format.
Moreover it says that the file or assembly "Microsoft.VisualStudio.QualityTools.Loadtest" could not be found at "C:......\CRM_Perf_BenchMark\OrderedTest1.orderedtest" Row 0 Position 0.
But the Projekt could be compiled without any errors.
The Performance Toolkit is installed in a virtualized Environment with Windows XP Prof x64 German and Visual Studio 2005 Team System German.
Thank you in advance.
