Hi McH..
This game is more stable than most may have you beleive. I run this game on two computers, both with Vista. I save very often and do not have any problems whatsoever. You may need to research what mods you are using for compatibility sake, and be sure to only install them while in port. I tend to think you should unistall SH4 completely and delete the old folder before reinstalling. There is a sticky thread to tell you the best, most thorough way to uninstall. I'm sure this isn't what you'd like to hear, but at this point, it's probably best. Forget your old saves, start a fresh career.
Knowing you are serving our country in Bagdad for us, I'm sure if you figure out what big mods you prefer, someone here would be happy to burn and mail a disk to you with anything you request. You'd be amazed how helpful folks here are. Post the info.
