I have got that CD but Maxon Cinema 4D won't work without a password :-)
At that time, you had to call a number and they would have given the password code.
And now?!?
Here you are:
16110502929-3973A7
Warning: that's a code that works with Maxon Cinema 4D version 4 that you found in super CD #27 of CU Amiga. IT's NOT a code for other versions. So it is legal.
