I Bought a unopened, new Resistance: Burning Skies for Ps Vita. I wanted to play the multiplayer for it so I proceeded to type the Online Pass activation code in. An error popped up saying: "The code you entered may not be correct or may be invalid. Please check that you entered it correctly (NP-8127- 8)". There is no 0 or o in my code so it can't be that I had those confused. Please help!
