Hey not sure if this is the right place to post this. I recently got Q4 second hand, i admit/ I patched it to the latest version, and it worked fine. Now suddenly it keeps asking me for the cd key everytime I start the game, no matter if on- or offline. ?When I enter the cd key it works, but it really is a bother. I do believe my copy is legit as i have a genuine looking case, disk and manual with the cd key sticker on it.
