Hi, I am having a problem with System Preferences freezing up when selecting Accounts. Everything else on the system works fine. I activated the Guest account for some file sharing then according to me deacitvated it but now it appears on my login screen however As soon as I select Accounts on the system preferences it freezes I will get an error message and the problem details (which I know VERY little about) show an Exception Type: EXC_BAD_ACCESS (SIGSEGV) and Exception Code: KERN_INVALID_ADDRESS If that helps. "Heres the copy paste Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000116dcf820 Crashed Thread: 0 Dispatch queue: com.apple.main-thread" I tried restarting or clickin on it but the same error message appears. Any ideas on how to get back the the default or fix this problem are greatly appreciated. Thank you!
