RMN20 means if you have vista sp1 is needed or if u have xp you will need xp sp3 and if u have windows 7 you need vista service pack 1 so what u do is find were the game .exe is right click set its property's for computability mode with vista sp1 it should work after that because i just did it and now it works. or if u have xp just compatible it with what u need the error tells u everything if u read it.

Well first we will need info about your computer....what kind of video card do you have?
DDR3 ram? OR DDR2
what kind of cpu
how much video card memory?
I have this same game and im telling you it takes a lot of computer to run that thing, if your computer isn't up to date i would not suggest putting the strain on your cpu or ram the game is very hungry for both, But get me that info and i'll help you out

You need XP service pack 3 or higher for the game to work
The error RMN40 is displayed when you have a service pack less than SP3 installed.. so try installing Sp3 and let me know :D
