Yeah not stern’s fault so I would stow the “I spent thousands of dollars on this and you fucked me!!!” Routine in any correspondence with Stern.
Someone had put a 3rd party software in there and you bumped it out when updated the software. Putting 1.06 back isn’t going to “fix” anything so I wouldn’t bother trying to find it or berating Stern to send it to you either.
Maybe start a new thread asking if anybody made an alternative mix they can hook you up with. Maybe the person you bought the game from has it?
