Cubase Elements 7 - Halion Sonic SE help


I am a teacher in a secondary school and we use Cubase 7 Elements in class.
Now due to the imminent closing of schools I want to get Cubase working on my laptop.

Cubase is working fine - but when I try to open kids’ coursework it says I don’t have the Halion sounds…

Can anyone help me, as I really want to get this sorted before the inevitable school closure.

Thanks :slight_smile:
