???Ahh... I have had this problem before. Hopefully you set up another account besides the Administrator account. Luckly I did. If you have more that one account on the machine you are going to want to log in safemode as the administrator. When you get to safemode you want to right click on my computer, then select manage. Go to the users section. Right click on the user of the expired password and then reset it. Also check the box "Password never expires" this will keep you from running into the problem in the future. Hopefully this helps!!
