Hi Martin, What kind of issue you have? Do you see the list of projects? Does the project start to open, i.e. view changes to 3D, but no 3D model is visible? In this case, do you see models in the left panel? Are they looking ok, i.e. not in red? If yes, on the right panel, switch to objects tab, select one object that you know that there should be. Then press space bar, that will zoom the 3D to selected object(s). Hopefully this helps. Best regards, Marko Myllymaa
