Turn PC off at 5am (fully off not sleep and no crash). Turn PC back on at 10am, see pop ups about rules for IE/WM etc. Look in my rules section and all are gone, totally blank. Vista Ult SP2 64, latest ESS. Feel the latest update must have caused it on a reboot as I had uses sleep throughout the day. EDIT : See there is a new FW Module, probably why above happened.
