I'm on a different computer right now considering I can't log on to my other computer. Yesterday I was on the admin account and trying to create another user when System Preferences froze so I forced quit the application and then restarted my computer. After it started up, instead of showing the list of users where you can log in, nothing showed up. Not even my main account. I can't access anything now. So I'm guessing all the accounts on my computer were deleted. Is there any way to reset my computer, or fix it? I've tried putting in a CD that should reset it but CD's won't work. Any help would be greatly appreciated!
