I've uninstalled all three extensions and restarted DW. This time there was not the Automated webAssist Manager start up... I still get the initial error but nothing else even after opening a PHP page. If I go to Server Behaviors and select Add then WebAssist / DataAssist / delete or insert they all pop out a greyed out <no behaviours> panel.
So the install is not complete but yet there is no automation going on. IS there a file I can delete to restart the install process?
