[my AO's wont work!]

i have the Sexy Walk AO and everytime i attach my HUD i can see it, but after each time i click AO ON or anything else on the HUD it does nothing. I've had this problem with multiple HUDs and AO's is there a setting in the preferences?

[how do i enable AO]

when i wear my AO's they wont work :( i can't click on the Hud either. i see it but it wont let me click anything. heeeelpppp T-T
