Have you downloaded the LeFemm Armour plugin? If so, is it the 1.1 version? If not, that's what could be causing the problem as regards the female imperial armour. If not, go to
here and click on 'plugins' on the left. As for the rest, as Theta said, it could be other plugins. If you have other plugins running, try turning them all off and starting a new game and see if you get the same problem.
