torque constructor problem

i think this is problably a easy question. ok i used quark for a long time, but then i decided to try torque constructor it is the greatest thing ever lol i love it :D. but anyway im making a hospital and i made a buildboard in milkshape 3d and exported it as a .dts file and loaded a static shape in constructor. i put it where i wanted it and sized up and moved it around and exported as a .dif and tryed looking at in torque game engine but the problem is that the billboard won't show up. everythings there except for the billboard how do i get it to appear in the game with the interior model?
