Marmoset weird specular

[Flakk]

In the paying version of the marmoset toolbag, the specular seems to read the specular exactly as I paint it. A black area on my texture doesn't do what I expect it to do, IE not reflect so much light. Instead when light shines on it, it simply turns...black. Same with light areas, they simply go grey/white (or whatever color it is in the map).
Going back to the old/free version it behaves as I expect.

Anyone know what I'm talking about and what I'm doing wrong?

Hmm have you saved your spec texture as a .TGA? Anything that's .PSD seems to go black and white in that weird style, if not I'm not too sure. I've had to play about with the specular settings in Marmoset seeing as they don't really reflect my texture map as they do in the UDK.

What I found out was that it behaves as expected if I add lights inside the program. It's the skylight that generates the weird specular :S.
And yes, tga:s.
