I think the FM patches page is still messed up - is your Help > Updates mechanism not working? If not, see https://helpx.adobe.com/contact/enterprise-support.other.html#framemaker for your Adobe Support options. I'd recommend using the email@example.com e-mail address as it reaches a team dedicated to Technical Communication Suite products including FrameMaker.
Amazing, "Help > Updates" didn't work earlier today, but now it works!
16.0.2 is now installing.
