Reply to NI Massive and Cubase

Hey

How do i get these two to work together? I can work them both on their own but when i want to use the massive synth as a vst i can't find it in cubase.

I understand your meant to save it in a certin file i believe but i haven't a clue where? Any help? I imagine its the same with all other non cubase synth. Struggling after years of just reason!

Cheers
