I think this game has the new Safedisc v4 or Safedisc Advanced (maybe they are one and the same?), that's why Clony and other ID progs can't find the signatures. The fact it has 00000001.TMP and 00000002.TMP files on the CD suggest Safedisc as well.
If it is a new breed of Safedisc it may take a bit more time for a crack, nevermind a 'working' crack
to appear.
