I receive error in CityEngine

[AleksandrKorshunov]

CityEngine. Can't open project. I receive error:

[Method: 'Default$Building_From_Footprint$Generate'] cleanupGeometry(): Whole geometry deleted, ignoring operation (keeping original geometry).    new_scene_engels.cej

I just create project, save it. Then close CityEngine, switch off computer. Switch on computer, open CityEngine project. Error
