I would call the free US tech support number when they're back at work tomorrow...
...but I would assume the message wouldn't appear unless something was amiss. Is it possible that you installed anything in other than the normal places, e.g., renamed the ArchiCAD exe, loaded Graphisoft add-ons from a folder other than the ArchiCAD add-ons folder, etc?
Cheers,
