Right so I've finally sorted it, defragged the computer and checked the files one by one, I'm just annoyed that the mod that doesn't work is the Wilhelmshaven port St Naz and Schluese, xtra ships mod.
One day I'll grab me a computer that can run it, but ah well at least its working now and I got to see the great work before the crashes
Thanks for the help everyone, this Kaleun can get back to hunting again.
