Norse Mythology Pack Music Not Appearing

Purchased the Norse Mythology pack expecting to get what I paid for. Textures seem to work fine with a bit of small glitches on the horse models. However when I went to go play I noticed that the amazing beautiful score had been replaced with base game music. When I went into the settings it says that there are 4 bugs, similar to those posted by another person here recently. They say something about a ui/enchanting screen pocket thingy that they cant find the control to and although they say nothing about the music, every time I play on it it uses the base game music.
