Yeah it's me again.
I have recently started skinning.
The skin I have a problem with is a reskin of the Mara Jade model for Jedi Academy (although i think the one for JO is exactly the same)

My skin is all finished, NPC works, BOTsupport works, but the problem is:
I cannot let the icon appear in the Multiplayer Profile menu
in other words: It is not possible to BE this new skin in multiplayer.

Does anyone have a possible solution?
(every reply is more welcome than no reply at all ;))

If anything, review another skin mod to see what's up. Compare a working one from yours.

Is it a custom icon? What did you save it as?

I saved it as
icon_default.jpg

and I compared it with the original model, but I can't quite figure out why that one works and mine doesn't

Hmm. Try this:

Open the game console when a level loads, see if any errors regarding the skin is found?

Did you try putting everything a .pk3 ?

Do you also have a .bot file for this?

The only thing the console says is
loading jk2 model
Yes all the files are in a pk3 file
Yes, a .bot file is present. I can fight the bot, but when I chop the head off, it stays off for the rest of the game, even when the bot has respawned.
