Naw, this is a Silent Hunter 4 and Windows 10 thread, and that's what you're dealing with, so leg irons are not needed... only manacles...
Now,
1. What is your mod list then... ??
2. Did you run the game OK without mods after first getting it installed?
3. Where did you end up installing the game?
4. Where did you get your copy from? DVD, Steam, or some other download?
