Ok I guess this is the help thread? Well, here's my question: I installed SimMars, and then later wanted to go back and just play the original, so I uninstalled SimMars. Since then, the music has not been working for me in SimCity automatically - I have to go to the audio options and hit 'Preview' on a song to get anything to play, either in region or mayor. Also, I later reinstalled SimMars and the music worked perfectly again. Then, after I've uninstalled it again, the music doesn't work. Do you know anything about this?
