Okay I see where I went wrong. I assumed there was only one Darkwraith UI mod and saw the file I mentioned in the previous post at the top of the Downloads section list, so I grabbed that.
It seems I should have grabbed the file named:
NewUIs_TDC_2_4_1_TheDarkWraith.7z
Will give that one a run. Hopefully it will revitalise my rapidly depleting enthusiasm to get to grips with this game.
I'm beginning to think the devs need an additional development phase for any future releases. This phase would include giving the game over to a select team of modders to tweak before they finally release it to market
