Hello, I bought Painkiller Triple Dose a while back and installed it and played the Single-player mode just fine. However, I could never take the game online on account of my terrible internet connection. It's been better recently, so I decided to join an internet game; however, I always get the message that my CD key is in use or invalid. As far as I can recall, my copy of Painkiller Triple Dose did not come with a CD Key, only the Penny Arcade poster and a postcard. Is it supposed to come with one? If so, should I consult the CD Key tech support topic and request a replacement key?
