There are..
1) Nebula 2/3 Free - This is the free version of Nebula. Anyone can download it, but it can only run programs (consisting of an .n2p file and an .n2v file) that are encrypted as free. In my signature, I link to my Nebula Free thread, which contains the only cab sim programs I've encrypted as free to date.
2) Nebula 2 - This is an older version of Nebula, and is less expensive than Nebula 3. This will run cab programs just fine. This is all you need. But, if you like Nebula and want to use a lot of the more powerful and updated features of version 3, then you'll want to go with version 3.
3) Nebula 3 - This is the big nasty bastard of all three. It has more to tweak than you could know what to do with, and has a greater learning curve than any of the other things.
Poi, your cab program is not encrypted as a free program, so it will only run on Nebula 2 and above.
To run the programs..
1) Install the latest version of Nebula 2/3. This will include getting the latest version, and doing the full email communication with Acustica Audio, which involves the transfer of a .ser file. This is their security measure. It takes a day or two.
2) Download the cab program.
3) Put the .n2p file in your Nebula folder's Programs folder. For me, it's c:\nebulatemprepository\programs. This is the sort of index file that the VST looks at.
4) Put the .n2v file in your Nebula folder's Vectors folder. For me, it's c:\nebulatemprepository\vectors. This is the actual audio data the VST uses.
5) Run Nebula 2/3, select the program, and enjoy.
