TypeMockRunner and NUnit.exe getting Exception.

When I run the tests under TypeMockRunner.exe & NUnit.exe, I get the following exception when running using the NUnitProject. When opening the assembly by itself, I do NOT get this exception. There seems to be an issue when the Test Assembly runs outside the NUnit Process. NO matter what option is selected, every time you run NUnit using the Project File, you get the exception below. Again, running the dll's directly does not give this exception.

Has anyone encountered this issue?
and resolved it???

Visual Studio 2008
.NET Framework 3.5
