I've got the answer of my failiure ( I think) . It's because of the silent3ditor remaping
- When I remap one of the 6 files (OK->save->close) and do the same to a following
the N° in the Remap case is the same as the one I firstly choose, But when I click OK for the remaping the parent id is totaly different than the one I have saved .....so all my file have parents id different

...No matter what I do
I can't have the parent id fitting as you show in the very first page of the Tuto.
Is there some setting to apply in the silent3ditor ?
I have the beta0.8
