pass a Nuendo4 Project to another computer

I have to pass a Nuendo4 project to a sound technician who also has got Nuendo4, but he told me that he can not open it because in the past when it did that, changed all the settings of his Nuendo.
EDIT: Loses all external VST chains, with their relative automations.
Is there a way to not have this happen?


thanks in advance,
