devilhood: I have just updated my guide with instructions on how to get the music working correctly on KeeperFX.
Maxo14: I've tried that method before and DAEMON Tools keeps saying "unable to mount" image everytime i try to mount the .cue file
Either way, i ended up downloading another .cue file that contains all the original files from DK and got it to work that way so thanks for the trouble.
I'm going to install DAEMON Tools Lite now to see why this is happening.
EDIT: I just was able to mount the CUE sheet first time (see attached screenshot). I have no idea why you were having problems. Did you remember to edit the file paths correctly? Anyways, I'm glad you were able to sort it out a different way.
