I could be a wrong MSVB file or even a missing M(icrosft) V(isual) B(asic) file. It could be missing because it is not on the cd by default and it's not even in XP so that would explain it. I'd go to there web site and see if you can download it and install it from there. They may be assuming you already downloaded something that installed it but obviously it's not there. They do that because these are quick and dirty programs to write to set up your computer to play the game. Even Quake III has one. There is a exe file and a few dll that come with the package. I'd say that is your problem. What you want to know what version. It could be VB6 or higher or even lower.
