SE V.20 - Welding Training do not work

[macimau]

Using Solidedge V.20 on windows 7 pc.
I've followed training instruction for welding parts in an assembly. The selection of faces (base and to be linked) is done well but when I start preview/finish, the program is not working, no weld at all and after some tentative it seems to crash.
Any help?
Thanks

Where would we be without sat-nav?
