I am the only user (and thus administrator) on my computer.
 Before my computer froze, I added an accent to my User
Name, and upon restarting it, I can not replicate it at
sign in. I'm not sure that I even know the password,
anyway. I have term papers due on Monday so I'm in a SUPER
MESS! Please help!!!
