We have a policy of not supporting unlicensed software here at VOGONS.
I suggest you asks the kind folks in the forum area where you downloaded the game for help on this matter.
And I regrettably also have to close the thread. Illegal downloads are often full of weird bugs due to errors in the re-packaging process. It is difficult enough to debug real DOSBox error without having to combat errors in the games itself.
If you can find a legitimate download (e.g. a demo) that exhibit the same problem, please come back, post a link to the demo, and we will do our best to help you.
