you can't use a cracked exe for a version with different protection, with a version that is protected by a different protection. means: even if crack for us non-starforced version releases, it wont work with a german starforce protected one
read this somewhere before for some game, dont remember which one, somebody bought a game in australia that was SF protected but another region versions got a different protection and therefor cracks for it, didnt work for the SF protected one. makes sense, because the protection works different, and SF protected games do not only have the .exe protected, there are some dll files and heck.
