Dragonborn parallax issues

[Lanpanic]

Ive been trying to use the Parallax Fix project - Landscape Dragonborn.esp by stasmonster and have been running into some issues.

 

Advice in the mod comment section said to remove the alpha channels from the textures being modified by the .esp

 

My first attempt resulted in this: http://imgur.com/jVOqkO4

This was from removing the alpha channel on all layers in the volcanic_ash textures

 

My second attempt resulted in this: http://imgur.com/TTgst74

This was from removing the alpha channel on just the first layer in the texture

 

I've been looking around and there's some mention of adding a height map to the alpha channel. I have no clue what that means (I'm not a major texture editor so I'm not in the know on the lingo, you know?)

 

I'm honestly at a loss. I've tried every thing I know how to do. I know there is a way to fix this but I don't know it. If a texture editor could helpfully explain what I'm doing wrong and what to do right I'd be deeply appreciative.
