unable to find n-track drums

Last night I decided to try and use n-track drums. I’ve seen it before (I upgraded my PC since then) but never sat down to use it properly. I’m using the latest 4.x version of n-track and although the dll file (and supporting files/folders) are in my VST filepath, n-track drums doesn’t show up in my VSTi’s or anywhere else. I tried moving the dll, changing the VST filepath, rescanning effects, but nothing seems to be able to find it. Any other thoughts.
