Hif olks. Sorry for the OT post, but this is driving me nuts. I've upgraded my computer to windows 7. 1. I've installed Superior Drummer v2.2, along with several expansions I've just purchased. I've been prompted to authorize all of the expansions, but not been prompted to authorize Superior. All of the exp kits have now been authorized, and I have the auth code for Superior, but nowhere to enter it. The interface looks exactly as I'd expect after correct authorization, but there's no sound. Any ideas? Cheers Darren www.karmistry.com/
