how to make a copy of gotij2 addon

[Gandalf{xan}]

hello out there!

i tried to make a copy of my newly bought gothik2: the night of the raven

i simply used clonecd to create an image, then burned that image

when i insert the cd, autostart apears, but soon after the installation starts the programm tells me to insert the original version of the game

any hints on how to work around this?
or which programm i should use to make a working copy

greetings gandi
