BTW, if you really need to have the Nuendo 5.5 activation code immediately, there is a workaround for that.
At the moment, all newly registered Nuendo 5 USB-eLicensers get a Nuendo 5.5 activation code right away. It’s only the already registered USB-eLicensers that take longer.
So, if you delete the USB-eLicenser from your account and register it again, you should get your activation code automatically.
