I messed around with it a bit more and I think I figured out what was going on. Only the VST2 version was getting blacklisted and I think it was because I moved the DLL into my drum plugins folder from my main VST2 directory. The update installer put the new DLL into the original location and it seems that was screwing up the scanning of the VST2 version. I really wish they would give you an option of where to install the plugins themselves if you can break them by moving them. Right now the installer only allows you to change the program directory. Cubase might have a nice plugin organizer now, but many other hosts do not. We shouldn’t be forced to haphazardly dump plugins into a folder and then good luck finding them when you’re in the DAW.
