Which version of Silent Hunter 4 are you starting with? If you have the most common older disk version, that would v1.3, the 'original' was like v1.0.1 or similar, while the 'modern' version is of course, v1.5 - do not attempt to apply the SH4 1.4 patch on top of v1.5, of course. The others, it's fine. Just checking though...
