Hot Fix

Hi, Just got done installing the Hotfix. I read that it would alter the aircraft.cfg file, in that I would lose all my addon livery aircraft. Well, I installed the hotfix and none of my livery aircraft were touched, in fact the aircraft.cfg file has yesterday's date. So this leads me to my question. Did the hotfix install correctly?. If so, why didn't it alter my aircraft.cfg file as stated and why is it showing yesterday's date when it was installed today? If I try to run the hotfix again, it states its installed.
