Haha, sorry, some of that went over my head. . . What do you mean starting from scratch? Yes, I did rename administrator as admin. No reason, really, I just wanted to I went into safe mode but no, it doesn't accept anything. Apparently I don't have the right to? I set it to autologin to the other account, because I thought I'd be okay since the user was in the "administrators" group. I've logged off and tried logging in as admin, but no go; it says I can't do that either. what do you mean by, "theoretically existing built-in" users?
