that's just a bug in the game i think. for technical questions with the game go to
http://www.anstoss4.com and then in the Forum. There are all bugs reported and u can find a solution easily. Hope it will help u.
but... the trick with copying a file to my hdd doesn't work at my pc. the "cd check" waits until the copying is finished and then.... "please insert original cd"... even if i try with the setup file (>400mb) he waits during the copying *grrrr*
any solutions?
