Hey
I just got a copy of Crysis 2, and installed it, and patched it to 1.4, however, I keep on getting the 'invalid' message when I put in my activation key, any ideas?

*EDIT*
I uninstalled the game and re installed it, however, I still get the same message, I brought C2 from EB Games....

Any help?

i have same problem. only that i have played this game for way over 40 hours, and i formated my hardisk. i re downloaded crysis 2 ( i have it on steam) and when it installs it should automaticly enter the cd key, but then i get serial used to manny times blablalba (error 1005)
