Error launching TypeMock Configurator from VS Tools menu

Hi,

I get an error dialogue each time I try to launch the TypeMock Configurator from the VS Tools menu.

The text of the dialogue is transcribed below.

"Please send the following error to TypeMock Support: The system cannot find the file specified
at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start()
at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)
at TypeMock.AddIn2005.Connect.a(String A_0)"

This problem appears to have started after I uninstalled a v4.1.0 version and re-installed a 4.0.3 version, though I cannot be certain. I am now running v4.0.3.

Environment as follows:
Windows XP Pro SP2
Visual Studio 2005
.NET framework 2.0.50727 SP1
