Texture/skin problem. Anyone help??

[MajorPayne]

Right then. In trying to convert my NTB630 bomber I've hit a slight snag. For some reason the bombers texture/skin is showing as though the UV co-ordinates are severaly screwed. I managed to fix this before but can't get it to work now and I dont' remember what I did before. Now I've followed Bex tutorial for model conversion and this is my last possible place to call for some much needed help.

 

So my question is, has anyone had this problem and remember how to fix it. Bare in mind that I do use Milkshape 3d for modelling and texture application and 3dmax 6 for conversions.
