Okay, I bought GTA IV complete edition second hand in a game shop, they said i didnt need a registration key, but obviously i did after all. Also, once i installed it the second (GTA IV) CD didnt work and it came up with "catastrophic error" and it quit. What do i do about this? Ive managed to install the Episodes for liberty city, but im not sure if it can work without me installing GTA IV. Ive managed to get past all the warning messages at the beginning, and then when the blue rockstar logo appears, the game crashes. What do i do? Thanks
