Drop-downs and Layout changed (following an update?)

First, my drop-downs have all been scrambled, and I cannot find the option to select a new UI layout in the preferences screen. I also cannot find the option to to edit Geometry, nor do I see any dForce modifier options. I have looked around for about an hour and have come up with nothing. Anybody know how I can reverse these changes?
Thanks for reading.

In Daz Studio? The layout should be in Window>Workspace>Select Layout, if not you may need to go to
%AppData%/daz 3d/studio4/
and remove the layout, menus, and toolbars .dsx files - with DS closed - then try relaunching to the default state.
It worked, thanks very much!
