Hello-
This is my first post. I’m using Cubase Pro 10, just updated to 10.0.4 hoping my issue would disappear but it did not. I’m using the new Komplete 12 CE/updated from 8. In plugin manager, all my NI instruments appear to be listed and there’s nothing on the blacklist. When I add a new instrument track to insert one of my NI instruments (Kontakt 5 for example) none of them show up in the list of choices. I’ve checked the plugin paths as well. I have the same issue w/all NI effects-- they’re listed in the plug in manager under effects tab, but are not available from the drop down when I go to add a new effect. I’ve been searching the forums but haven’t seen this problem…there was a reference to my processor being AVX compatible on the NI site, but I’ve confirmed that it is compatible (i7-3770k 8m cache up to 3.9 ghz). I’ve confirmed all my plugs are 64 bit. I’m able to run Kontakt 5 and the instruments in standalone, just not in Cubase 
…I can’t figure it out. Please help!!
