No, it's possible, it's just very complicated. It's definitely above my skill level and patience-tolerance. If you have an original v1.0 disk, and you've upgraded to v1.1, you are going to find some very frustrating aspects of the game... You are better off with v1.5, which has the Uboat Missions, but if the money for that is just not to be found for that, then at least apply the
Silent Hunter 4 v1.4 upgrade patch from subsim dot com here. I'm not even sure if it's available on the Ubisoft site any longer...
