First time messing around with game, help?

[Siba]

I've been trying to make a new ship out of stats and xfiles already in the game. More specifically, I'm trying to get the fazrah cruiser model, add a few slots and tweak other stats, then make it purchasable at a terran shipyard.

I can't seem to do this though.
I've made copies of the xfiles, portraits etc, pointed the spaceobjects xfiles and main purchase ships player txts to the new xfiles and portraits, and then used slot modder to add a few slots.

When I make a new game or load an old one, the ship never shows up. What could I be doing wrong?

I reordered the configuration slots to go weapon > shields > armor > inner hull > outer hull, just like the default ships order. However, I still can't get the ship to show up. As far as I know, all of the pointers are correct to the different files. I've also made alterations to the firing arcs, if that makes a difference.

Can anyone tell me what I'm doing wrong?
