Typemock version 7.2.0.0 - Assign Parameter Error

Hi,
I am using the latest Typemock version 7.2.0.0 running on Windows 7 64 bit in Visual Studio 2010, .net framework 4.0.
I am using fluentvalidation library version 3.3.1.0. (http://fluentvalidation.codeplex.com/)

I have encountered the following error using the code attached. Prior to upgrading from 7.0.8.0 to 7.2 I did not encounter the error. I am trying to use the 7.2 version as it allows other tests to pass under the recent Microsoft Security patch.

Test method TypemockTestValidation.UnitTest1.ValidateAssetDetail_Should_Throw_Validation_Exception_If_The_Model_Is_Invalid threw exception:
TypeMock.TypeMockException:

Would appreciate your thoughts.

Thanks,
