Tattoo: 3ds file format problem

I downloaded Tattoo and am trying to make a texture for a model I did in TurboCAD Deluxe v.12 but for some reason the brushes won't paint the model. I tried one of their examples and it was possible to paint on it, but whenever I try to use my model, all I see is a black silhouette and whenever I try to put my brush on the model, my model just lights up instead of the brush conforming to it's surface. Is this a specific problem with TurboCAD's exported .3ds files? Even the example is a .3ds file and It works fine.
