I literally just recieved a factory sealed copy of Gal Civ 2 from Amazon. Every time I try and register it, it says the key is invalid. I'm staring at the sticker on the back of my cd case as we speak. No variation of the letters and numbers seems to be working. Any help would be appreciated. From what I've heard the original version of the game is kinda buggy, so I was hoping to DL the updates before I bothered playing.
