i can't use archicad 10 because when it opens new project, it hanged, saying something about open GDL problem or something. if i close the work palette( the one on the left side, containing walls, windows, etc commands) i can use it on floor plan view, but i can't open 3d view because there are yet again failure and failure reports. now i have to open my old files from archicad 8 and from there then i can use archicad 10. but that is a bother... can you help me?
