SeteSete:
You are missing one or more of the libraries that that file uses, in the AC 12 Help files see: Configuration : Libraries :
Missing Library Parts and the Library Loading Report Palette. If the file was created using an earlier version of ArchiCAD, then either the earlier version library or the migration library for that version should be loaded.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
