I found something that underlines what I assumed:
http://thelostpatrol.knagge.com/guestbook.htm The webmasta wrote there... Hi, it`s like this... 1) There are two versions of the game: A pirated (buggy) prerealese version and the final sales version. Various different cracks were spread back then, most people seem to know the prerealese version. 2) There is NO WORKING CRACK of the final sales version (the 100% working one with the green timebar on top of the screen). People thought they past the Copylock protection, but it`s more tricky this time and takes effect when moving to the second screen (your men go nutz...) Get your hands on the prerealese version, it does work, but you may notice some bugs there (e.g. minefield section doesn`t work). On the other hand, some prerealese cracks do not seem to work aswell... Maybe you can find the original disks at ebay... uhh, it`s tricky! So there is no other way than the original version.
