Having problem installing skin.

Hi Peeps 🙂 I'm having probs installing a Spartan Executive Skin. I've done everything it says in the installation a few times, but alas, no result 😞 Obviously, I have the Spartan up and flying in the livery it came in, and even though I've installed other liveries successfully, this one, I just can't get to work.
Right then, after downloading and unzipping, I start with a folder...NC17616 and ofcourse the read me file. After opening the file, it now contains another one..... texture.NC17616 this contains bitmap images, I take that this go'es straight into the Spartan folder thats in the FS9 aircraft folder, because it say's nothing about it in the read me file ???

Here is the read me file.

INSTALLATION
Cut and paste the following text to your aircraft.cfg-file.

NOTE! Replace the X on line 1 with the number in order of
your file - example: if it is the third texture, replace X with "2"

---CUT BELOW THIS LINE---

[fltsim.x]
title=Spartan 7W Executive NC17616
sim=spartan
model=
panel=
sound=
texture=NC17616
kb_checklists=
kb_reference=
atc_id=NC17616
ui_manufacturer=Spartan
ui_type=7W Executive
ui_variation=NC17616
description=repaint by Edward Cox
atc_heavy=0
atc_airline=
atc_flight_number=

---STOP CUTTING HERE---

I've done the above, and now the Aircraft CFG file now looks like this....

[fltsim.0]
title = Executive VC
sim = mspartan
model = vc
panel = vc
sound =
texture = urs
panel_alias =
sound_alias =
kb_checklists =
kb_reference = spartan_ref
atc_id =
atc_id_color =
atc_parking_types =
atc_parking_code =
ui_manufacturer = Spartan
ui_type = Executive-VC
ui_variation = Original
description = Spartan Executive-VC

[fltsim.1]
title=Spartan 7W Executive NC17616
sim=spartan
model=
panel=
sound=
texture=NC17616
kb_checklists=
kb_reference=
atc_id=NC17616
ui_manufacturer=Spartan
ui_type=7W Executive
ui_variation=NC17616
description=repaint by Edward Cox
atc_heavy=0
atc_airline=
atc_flight_number=

As you can see above, I've changed the ( X ) that read [fltsim.x] to [fltsim1.] is this right ? considering that the one above it is a 0 (zero) ???

When I start up FS9, and go to choose the Spartan, the aircraft model comes up as ......7w Executive and the variation comes up as ....NC17616
but no aircraft

Obviously something is wrong somewhere, I know it all sounds confusing, but I've tried to explain the best I can. The skin I'm trying to use is this one found on the AVSIM site ...........
