Sorry lads. I ask a basic question which remains unsolved. It seams to me unless you are an experienced Blender user with very technical problems that there is little interest in offering help. Pity because Blender has a lot to offer.
Sorry but I uploaded the mesh as asked and I can open it without any problem. I really do not know what to do next.
Add your blend file to pasteall.org and add a link to it
