thanks for your reply luciel!
i believe the patch is out until mid-september. it fixes a nasty bug which wouldn't allow ati-users with catalyst 4.3 (and newer) to start the game. afaik only the game-exe (start-file, protected) was replaced.
tried the two v.1.0-cracks with the patched game, but that doesn't work. i thought i ask if anyone knows something about a crack, because the patch is out for some time.
of course i know, that this game is no real blockbuster-title, so eventually a crack will never appear.
anyways....if no crack appears, i have to play with the disc inserted...
