What I meant to say is.
I have done all those things, essentially starting from scratch. iRite is the only extension I have currently installed.
I followed the ipvac instructions very closely. When I said backed up the config dir I should have said re-named it, making Dreamweaver re-create it. Just in case I gor one of the steps in the ipvac ibnstructions wrong, I am doing the whole thing again including re-activating iRite.
The end result is exactly the same.
