UV master unwrapping problem

Hello there,
i have a problem when trying to make uv’s to a model. In UV master, i Work on Clone and i Protect and Attract in order to get the right seams. But as soon as i unwrap, i get an unreadable map. So i enable CheckSeams and see a complete mess. The seams are exploded in spots and get this black noise. So the map is chaotic.
Any suggestions ? i’m pretty stuck…
See pictures
Thks a lot

Many thks
