I have no bad sectors... The file can be open, I may have worded that wrongly, but only one deformed cyclinder is shown in wireframe with no shader. I can see all the other objects in the Hypergraph, when selected I can apparently move and transform them in the view port but they are not showing up. Also I can assign shaders, but again the objects don't show. Only the one object that loads renders... Any more idea? Cheers
