Ok, so i'll give it an other try. What about the rotation tool (c) is it fine??
@Nedarb: I unkeyed scale before rescaling and keyed it after i did my work.
@Ace: This time i ask

Move Joint Tool is ctrl+j, i'll try it. But what is PPG??
==EDIT1==
I'm afraid of doing something wrong again. I loaded the templated into my XSI advanced, since i can not open the old scene i made in mod tools 7.5.
I have both opened (old scene in mod tools 7.5 and the new opened template in XSI advanced). I wanted to adjust the bones so they are at the same position as in the old scene. But when i change the rotation values in the property page, nothing changes. The bones are still at the same position. And yes i unkeyed them.
==EDIT2==
Ace and nedarb you are my heroes

But nonetheless, can you please answer my questions from edit1 ?
@Ace: seams that the softskinned didn't work for me either.
