Battle Pak One

I recently bought the Battle Pak One music, and for every outpost/city/area in which the music should be updated, the only tracks that play are "Arrival in Silverwood" and "Riverside Province", and whichever one plays seems to be randomly selected.

I don't know if this is a common problem, as I got no input in-game.

I'm not entirely sure if this is the right place to post this, but any insight is very much appreciated.

Did you register it using the Media Player? It's kinda silly that you have to confirm registration outside the game to make it work, but I had this very problem until I did this.

I believe that I did, but I'll delete and re-download it just to be sure.
