I have the same question as Hay - and it remains unanswered. My Maschine 2 64-bit does not show up in Plug-ins at all now after upgrading from Pro 8 to Pro 9 yesterday. I also have NI Komplete - most of those instruments show up, but not Maschine. Maschine 2 is in the same folder as the rest of my NI products, but does not even show up on the Blacklist, so there’s no reactivating.
Nothing on my PC has changed except the upgrade to Pro 9, plug-in paths are unchanged. Also, I did run Native Access, everything is latest/current version.
Please help, this is a show-stopper!!!
UPDTATE: Solved by adding the correct path to VST Plug-in page. Cubase lost my paths on the VST Plug-ins during the upgrade. It seems to have grabbed an old version, because there were also paths listed that I’ve deleted in the past. I would say this is an install package bug.
