It is often NOT necessary to immediately think of a re-install.
OFF has two buttons in "Workshops", which made a reinstall unnecessary for me at least twice.
If the OFF Manager is corrupted, the button "Reset OFF Manager" should help.
If it lies deeper, in CFS3, then also press "Reset CFS3".
I recommend to try this BEFORE going through a full de- and re-install.
OFF has Master Copies of important files, which seem to be copied and
made into the basic files which have gone haywire.
But before all this: deactivate all mods.
When everything works again, you could try to re-activate one mod after the other
and see which one causes the problem.
