Having the same problem, only it happens when I'm starting a game. I've been playing consistently for the past three months and clocked 5 days of play. It only started happening this morning. Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000000 Crashed Thread: 3 I've tried re-installing, deleting the preferences file, turning off the sound, and everything that has been posted here and it's still not working. Any ideas?
