I have Windows 7; I forgot my password & I'm the administrator on the computer. This program is supposed to unlock the account for you or crack the password, isn't it, or am I confused? This is, I believe, the third program of this type I have tried. Everything starts fine, downloads quick, but when I go to "run" the program, it, on all three programs, asks me for the administrators password. I do not have the password which is exactly why I am trying to use the program in the first place! I'm just so confused. Am I doing something wrong? Or does this program just not do what I think it does? SOMEONE, please help me.
