I have followed the guide and renamed events.dat, added a music folder in SOUNDS, put my mp3's into it, gone into descr_sounds_music.txt and put into the command lines the names of the mp3's from my music folder, and it worked! The music i want is now in the game, but the problem is, no other music works anymore.

The original music will not play. All i added was some battle music, and it works perfectly, but the campaign music, victory/defeat music doesn't work, nothing else works except for the ones i changed. Wtf is up with that?
