I did exactly as that readme instructed (tried Steel Sound 1.1 mod)and even tried installing the polygon packs you mentioned.None of the 1.5b missions work.Same 001 Error.
It would be nice to have an accurate install list as a sticky somewhere along with what is actually needed for the english version to work right.
Hi,
Your orginal list of mods should be all you need:
Unofficial Patch SF v0.1eng
Steel panzer Mod v1.5beta
SPM 1.5beta fix
SPM 1.5 NTA 1.3
If you're running on Windows 7, you might want to try installing SF in some folder
other than 'Program Files',
