Never happened to me but I think I know what is the problem. You need to migrate the libraries from previous versions to the current version, but first; make sure that those libraries are installed on your hard drive by going to the ArchiCAD folder on your system and checking the Library folder, there you should see all previous library versions.
I hope this helps.
