I tried this but it did not work. I have also tried to reinstall windows 8 but the result is the same, i.e.:
It works flawlessy when I boot into OS X but not when booting Windows.
A strange detail I fond, the free version is easier to booth see and connect to.
I Will not spend more time on this until Steinberg make a new release. There are competitive producs that works on my Windows installation so I will upgrade one of those instead of fighting this beta software from Steinberg.
