OK, Here, try these.
Everything has been re-scaled, re-textured, and re-positioned.
Notice in the Blender screen shot that the textures no longer have ugly visible seams. (The middle black one is the low-poly MD2 without any of the four textures applied, don't worry about it.)
Edit: I exported the textures as JPEGs, I can't figure out why they don't display properly in the game (shown in the other screen shot, I edited the .ufo files to try to test in 2.3.)
