I have managed to re-install MSE since my last post but if I click on 'Update' it will only download definitions up to 1.143.376.0
I have manually updated to the latest definitions ( 1.143.436.0 ) using the following link.
Thanks for the link. My MSE was on the .376 def also and would not update (appeared to d/l, but did not update) using the "Update" button from within MSE. I went to the link and it updated successfully to the .455 definitions.--
