Do this before running Cubase with v3
If you don't own Vectron, do yourself a favor and delete it from the device list in Pulsar 3.0 before you run Cubase. Otherwise, when Cubase loads XTC for the first time, it asks your for your Vectron key code and I couldn't find a way out of it without a hard reboot.
