I am replying to my own post only because I should have mentioned that there is a detailed FAQ on the website that will answer most questions about the software. The thing I did not mention is that you will download an ISO image that needs to be burned to a CD. If you do not have software to do this you can download a program called ImgBurn from here.
http://www.imgburn.com/index.php?act=download Just choose one of the mirrors to download from. I suggest mirror 7 The ImgBurn mirror. You will need to install the software to burn the ISO image.
Once the image is burned to the CD you will need to leave it in your CD drive and reboot.
If your computer boots into Windows and not from the CD you will have to reboot again and change the boot order of your CD drive. Make sure the CD drive is the first boot device. The other option is some computers have a keystroke (the F12 key??) that allows you to choose what device to boot from. Choose the CD drive and then follow the directions the software provides. Since it is the Administrator account you need to reset make sure that you have that account chosen as the account you want to reset. The software will not show you what you password is, but it will let you change the password.
I hope this helps.
