If ur talking about the 1.4 patch for Stock SH3 then yes i have had problems with it. When i tried to load it, the program said the Eng Help file was incorrect or something like that, I asked about it on the forum and people replyed saying i should re-install SH3 again, like Delete every aspect of the game, start over from stratch and install a new copy, then try it again, and if that doesnt work, just load the first patch the 1.1, then load the 1.2 patch, then the 1.3 patch then finally the 1.4 patch. When i did it before Ubi didnt have the links for the 1.1, 1.2 and 1.3 patchs but copy the 1.4 patchs link and subsitute the 1.4 at the end of the link with the 1.1 or the 1.2 or the 1.3.
It should work, if not just ask another question
