There are certain pre-requisites involved in using any mod, no matter which. Number 1 being, what folder do you have SH4 installed in? You cannot be in a "Program Files" folder, even if you have Steam, and the path to the game is "C:\Program Files (x86) \Steam \SteamApp \common \Silent Hunter Wolves of the Pacific". You Steam Library folder has to be something like "C:\Games \Steam..." or some-such. The same holds true for a Ubisoft or Amazon download version of the game, as well as the disk version. Second, after activating a mod, you almost always have to empty the game's "Save" folder, which by default is the "C:\Users \UserName \Documents \SH4" folder, with "UserName" being whatever username you use to log-in to Windows with.
If you navigate into that folder, you'll find a "... data \cfg..." folder structure. Delete any of those folders, and that will clear the game's information, which it will then rebuild the next time you start the game, only this time, it will pull in the newly activated mod's information, and not what you had previously. This of course, does lose all of your game progress thus far, and will re-set all of your in-game options back to their default values, including the screen resolution. The use of
MultiSH4 can help in this regard, but would be considered an "advanced" technique initially.
If you would, post back with the location of your game's installation folder, some computer specs, such as cpu & amount of RAM, and use JSGME "Tasks..." "Export activated mods list to --->" and "Clipboard", then paste that info in also...
btw: "Welcome to SubSim!!!"
