surface modelling loft function

Hello,

I am  following a tutorial to make a speaker with surface modelling (tutorial attached)

In the beginning when i make the first loft something is going wrong. The shape i get is different from the one i should get regarding to the tutorial (see page 16).

You can also see the problem when you look to the top view i got versus the top view that is showed on page 26

Maybe someone can help me with this, i am searching for some hours but i can't find the solution.

Kind regards,

Bryan
