Combining Skins Doesn't Work?

[EB64]

A few days ago, I found the Transparent Map Tracker skin.
It's something I've wanted to see for a long time.

I currently use NUI(http://www.lotrointerface.com/downlo...info.php?id=18).

I tried putting the TMT skin inside the nui skin, and it did work that same night.

But now, for some odd reason, it does NOT work.
In fact, the nui skin doesn't even show up when combined with the map tracker one. I've tried it several times and it's the same thing every time.

What on Middle Earth would make it work one day, and not work a few days later?
They do seem to work separately, just not when I combine the two.
Can anyone help me out here?
