First I did like "Nervouspete" wrote earlier:

"If you want this wonderful mod to work in Silent Hunter 5, simply delete the music folder and its music.cfg file - found at ...data\sound\music in the mod directory. Otherwise you get CTD's upon loading the sub-pen."

Then I used jsgme to activate it. Some of the songs I also like to have on my gramophone, so the wanted melodies can easilybe copied, and put into the gramophone folder, like data/sound/gramophone.

Actually I didn't delete the music folder, removed and stored it outside the game folder (where ever u prefer).
