hi. i'm not sure if this is the right place for this but here it goes. somehow my keychain is locked and in the prefs the list is empty. i try to repair and it says it can't find the "login.keychain". in the utlties fldr the file is"login_renamed.keychain" and when i change the file name to login.keychain it reverts back to the first as soon as i hit the repair button in keychain 'first aid'. i copied the file too thinking it was just a glitch and it renamed that one too. any advice? thanks.
