@GRODD you need to rescan. reading through this should help you out here, I can't exactly remember the process as I made a instance of the vst into a rescan only version to save me some hassle a long time ago.

There are still versions that you mention available if you look
As for OSX not 100% how it deal is there.
However keep in mind a few things. The version/program/presets itself has never been FULLY reversed etc or whatever you want to call it and keygen simply provides a ser file that has some issues with activating certain products & libraries. Certain things have still not been available to users.
The version you mention had NO factory presets & is now pretty old.
I'm in no way trying to demean the accomplishment etc but would strongly advise to look into somehow considering purchasing this product whenever you & if are ever able.
The free version they kindly offer is also pretty damn good even though the factory is slimmed down etc. The version you are talking about can also only load certain 3rd party libraries up to a certain date in time & can't do LOADS of other way useful things like use of the amazing AQUA plugins, running the most up to date libraries, CPU issues & the list goes on & ON.
Other 3rd party libraries need a ser file and just about ALL of the libraries developed nowadays which are mostly amazing will not work with that version. Whilst useful of course to a great degree the libraries nowadays are way ahead of the older ones.
Nebula 4 is now here with an amazing GUI & huge improvements to CPU, Aqua engine and so much other stuff. Pretty sure they will be offering a free version of this also.
I bought this program way back & it now runs real smooth and is most probably THE most useful tool out there in terms of music production. It's basically so powerful & versatile.
The customer service is now WAY better than it was & they now sort problems in hours. Probably the best purchase I've made outside my DAW itself like Reaper.
I'd strongly recommend getting in touch with them & discuss the possibilities WRT purchase as they are extremely helpful & offer substantial discounts.
So all in all, it's still around & usefull to a degree but we NOT ALLOWED to offer links here & it's for sure one of the tools you definitely wan't to consider trying to purchase if at all possible as the technology is moving on real fast.
Best of luck
