Ok well in short the fix for this would be to get this launcher
And do the following every time after you use the SS_setup.exe:
- Launch Stainless Steel with v1c7r1x's launcher once, so it can recreate the missing strings.bin
- Exit the game.
- Launch Stainless Steel from it's own launcher (SS_launcher.exe) and play.
Remember that everytime you activate/deactivate submods, change campaign era, etc using the SS_setup.exe
you'll have to repeat the process above.
Thanks to capablecenturion for finding this out.
Alternatively you can extract these
