I'm afraid that most are running either v1.15 or 1.16 of FPSC and use mods such as Project Blue, Fenix, etc. Unless there is a user that uses FPSC v1.09 and can help you with your issues, you won't get any helpful instructions.
Most of the mods are pretty simple to install. You copy the FPSC-Game.exe over from the mod archive to your FPS Creator folder, over-writing your current FPSC-Game.exe. Be sure you rename your default FPSC-Game.exe with a .bak or .org extention, or copy to a folder if you need to restore it. S4 Mod had some files that also had to be copied into the gamecore/guns folder. As I said, most mods have a detailed readme or install instructions.
I tried it, but it will not run on my v1.16 and I'm not reverting to an older version due to the development we have going on. I wish I could be more help. I will make a recommendation to you for what it's worth. Why not try out Fenix mod to get a handle on the usage of a mod, then if you like that, consider purchasing Project Blue. IIRC, s4 had his mod integrated into Project Blue.
