Please use the latest updates of reaktor, install 3.05 and then the update 3.07 008. After installing the 3.07 008 copy all VST plugs from the Reaktor 3.05 folder to your Cubase/Logic VST folder manually. It might happen that audio does not get correctly into an fx instrument. If this happens: press the new-instrument-button in the main control panel of Reaktor. It is important to use this *button*. Then reload the fx-ensemble. Audio should now run correctly "through" the instrument. If not: delete the wires in the ensemble top level structure to and from the fx-instrument and set them again.
