Is ArchiCAD in the same folder as PlotMaker? Is it a clean install? Have you run an updater on a modified installation? If you have changed the names of the applications (or made multiple copies) the updaters don't work properly.
I just updated the file about 2 hours before I got the error message. I had to go in a just create a new layout book. That seemed to fix the problem. But, who knows how long that will last.
