I am in dantes theatre and I went to the terrorist data hub and extracted the data and killed all the guys. Then I was told to move to the extraction point. I didnt go up the ladder and across the catwalk because I knew the door was locked before. Instead I went through the theatre the way I had come from and I got to the point where it said saving data so I thought I was going the right direction. Now it says I objective again is to go to the computer and extract data, but when I get back to the computer again I can't do anything there. Did my game mess up or what do I do?
