Hi, …
Not many, afaik.
But if you can get hold of an empty eLicenser dongle you might be able to download a Nuendo 8 Demo version which runs for 60 days.
Or for minor changes, get Cubase Elements, which saved my behind a few years ago on a holiday…
Else, have the dongle sent by mail or courier.
Hope you make it, …
Cheers, Big K
