I have had some serious problems with this upgrade. Steinberk replied to my support e-mail and gave me a second activation code and it got a whole load worse. Groove agent had gone awol along with the new reverb plus retrologue. To make matters worse I cant at the time of writing re-install my old copy of 7. Looking on other forums this has been happening for sometime and they still sold the upgrades. I've got to back up all my projects to an external drive and manually remove all cubase stuff. Damn never get probs with Propellerhead.
