Ok I seem to be suffering the same problem, only installed Daz3D couple of days ago, definitely had an animate options tab next to the Timeline tab, and even successfully used it to crate some walking animations, this was last night.
Cannot say this 100% but am pretty sure it said Animate Lite and not Animate 2 on that tab.
For certain I have never tried to input any serial number for it into Plugins window, only discovered that plugin window just now after reading this post, and the Animate thing has been missing since I tried Daz3D again today.
When I open the Plugin window it has the Status Icon for Animate 2 greyed out and in the info pane at the bottom says ‘Evaluation Disabled’, this has to be some kind of bug?
Not very impressed f your telling me that’s it and there’s nothing you can do, do you think after 30 days it will revert to this Animate Lite function anyway, or will my copy of Daz3D now never have that?
Have attacked a picture showing my Plugin window with the Animate 2 plugin selected.
