Hi, having just recieved a copy of Rail Simulator in the post today from Play.com i am not happy. I cant get the game to install at all. I enter the CD key found on the manual, and then a cmd box pops up for a split second and then nothing, im just sat staring at the deaktop. Computer is only a month old and runs Windows Vista Home Premium. I have tried running the setup file from the CD instead of letting auto run but still nothing, and i have disabled any firewall and anti virus software.
