Forum:Help computer glitch!

So I was playing on a new energy weapons character recently and I started "That lucky old son" quest to arm Eulcid's C finder. I got to activate the terminals but when I shoot the hostile dogs gaurding them the whole base fires at me, so I activate the terminals without killing the dogs but when I activate the terminals without killing the dogs no computer screen appears i think so what but later on when in the tower I'm fighting some robots and I bring up the scope on my Gauss rifle and you know what a blank computer screen appears instaed of the scope. So after a bit of nerd rage I load up my guns profile and bring up the scope of my Anti-mat rifle and you know what a blank computer screen appears! If you could help solve my problem I would much appreceate it(I'm on Xbox360)(I also lost Arcade gannon aswell)
