@tfh: Thanx for trying. I tired two different dutch versions (one 360 kb version and one 720 kb version with more files (don't know why that is). But still the result was the same. I also found a french version (720kb) which I will try later. For some reason you can't get past the harbor. Could it be a bug ? Does anyone have the original and is willing to try ? The link hydragon posted shows the walkthrough so you can proceed quickly to the harbor chapter.
Is it possible that it is some kind of copy protection your running into? The game was originally copy protected from what I recall, and it may have only been partly cracked?
Just found an really old copy of the dutch version of this game.
It started without problems and I played chapter 3 without any problems on my Turbo-R using the PPT walkthrough.
