Having problems downgrading to 6.1.2

Here is the full error message when I try to run an isolated unit test now:
Test method ****.UnitTest threw exception:
TypeMock.TypeMockException:
*** Typemock Isolator is not currently enabled.
To enable do one of the following:

* To run Typemock Isolator as part of an automated process you can:
- run tests via TMockRunner.exe command line tool
- use 'TypeMockStart' tasks for MSBuild or NAnt

* To work with Typemock Isolator inside Visual Studio.NET:
set Tools->Enable Typemock Isolator from within Visual Studio

For more information consult the documentation (see 'Running' topic)

Hi,

I imagine that by "enabling/disabling isolator" you mean the add-in.
Please open Typemock menu in VS, if the first line says enable mocking - click it.

Let me know if it helps.

Yes, it is enabled there, but in the test runs, it insists that it is disabled.

Is there anything add'l I can check to get to the root of this problem?
