Are you trying to use
JSGME version 2.6? If not,
get it and use it. What is the path to your game install? The game's install proggy defaults to "C:\Program Files (x86)\ Ubisoft \ Silent Hunter..."?? What we're really curious about, is "what do you mean, 'Won't work'?" ie: "JSGME won't start" - or else - "When I activate the mod with JSGME, the mod isn't showing in SH4"?
