Try downloading manually VbMaleStrong.fo3d and _FOHuman.fo3d and put in critters folder. Only those contain the settings on the animations. And the animation files are male_walk, male_use, male_knife, etc. If you have those it should work. Check it.
There are other armors, but you need to select them by console command. With admin access:
~run debug SetCritParam (critID#) 153 (armor#)
where (critID#) is your ID, usually 1.
153 is the Armor layer.
(armor#) is the armor number. I think there are from 1 to 10. Set it to 0 to reset.
