MMA updated to 1.1.3.0548 the other day. I went on an 8 hour road trip yesterday and was left without any music as MMA crashes on startup now. I have tried reboot, clear data, force stop, and still can't get into MMA. I listened to music last week and it worked fine, so I believe the update must be the issue.
