Apparently on my end it was an issue with needing to reinstall my video card drivers of all things.. I guess I've heard of weirder things! SH4 and 5 now work though. So bizarre.
I'm running Windows 10 though and both game folders are in my Steam folder. Something like D:\Games\Steam\steamapps\common\Silent Hunter 5, I believe off the top of my head.
