i load the start menu, press campaign, choose the level forerunner and it responds back to me with the message" player is missing downladble content"(i am the only player), i have installed disc 2 and have played through the prologue and 2 first campaign missions, there are no scrathes or any damage on my disc, ive tried playing through requiem and when i finish it immediately brings me back to the start menu without even trying to load the next. I hope you have a soution to this as my first thoughts of this game are pretty muzzled right now. Look forward to your response.
