How to back-up Knights and Merchants

[Bobotaculys]

How can I back up Knights and Merchants (a quite old game), when I try to burn it with Clone CD, it will only copy the sound files on the CD :confused: and if I try to burn it from the hard disk with Easy CD creator 4 the files on the CD don't work.
PLEASE help me.

What is its protection?
Try and find out with clonyxxl or Protection_ID.

If you cannot find any protection use Alcohol with "General protected CD".

The game has nog protection (I used ClonXXL)

If I use Alcohol120% with general protections, it says I need to put a bigger disk (800MB +) in the diskdrive?!? While the real disk is only ±300 MB!!! This is because there are some audio files on the disk, but why they become so big while burning I don't know.
Can somebody help me?
