Recently bought the soundtrack for Another Crab's Treasure and have found that the Steam App won't play the music? I can browse local files and play the music from there but the actual app doesn't do it. The player just doesn't move when I press play and I've tried everything to fix this. I've made sure to have the latest steam client, I've tried steam beta client and I've even reinstalled steam which has not done anything for me.

Has anyone any idea or suggestion on how to fix this issue? Google has very little / if at all any forums or topics or discussions regarding the steam soundtrack player and I'm not even sure if I could get a refund for a soundtrack I can't play via the service I bought it from because it's technically DLC...

Any help is appreciated :)
