It's not tied to your thing. I already HAVE Cereburus Network..I don't know why you guys keep claiming I need the disc...or whatever. I understand it needs to be authorized -I already said that it does from the Private Terminal.
Also it never took me to their website - that's a load of crap. It made me enter the code directly in-game and when I hit DLC on the launcher -it takes me to their dumb site without any info.
