Forum:Glitch, Please help

Hello there, I am having some trouble with my fallout new vegas and I was hoping that someone could help me. I just finished old world blues and I would like to wear my Stealth Suit MK2, one problem, if i am not dressed as the ncr they will try to kill me. The weird part is that I am idolized by them. The exact same thing happens for the BoS. If anyone can help me, thank you.
