I've followed all the instructions, as show in this video here:
For some reason, my pack isn't show up in my inventory in game. The mod builder tells me that the mod is built and ready, but alas, nothing in the game to confirm that.
Here's an image of the dialog box that confirms that the pack has been built.

And here's another one showing how the mod is setup.

If anyone could help me out, that would be wonderful!
Any advice would be most appreciated, I've been trying to get this working for a while now...
