Open ff.files
Hello, I noticed that I cant open any Black Ops 2 fastfiles with FFViewer. I always get this error ( used file: common_zm.ff): "Error loading .FF: Bad state (incorrect header check)" . If I press the OK-button it says me that the file couldnt be opened because the file C:\...\common_zm-extract.dat couldnt be find. Maybe I asked a stupid question but it would be nice if someone could help me to see the files inside
