Forgot password can't log-in help please

I have tried all of the methods listed unsuccessfully. The problem is with each one the box I receive has only a password space. There isn't a space to enter user names. The box I receive says "Windows Xp Startup Password"
Below that, it says "This computer is configured to require a password in order to start up. Please enter the Startup Password Below"
Below that, "Password", then a white box with my cursor flashing in it.
Below that, I can click on "OK" or "Restart".
When I try to reboot in safe mode with command prompt, I don't receive a box to enter a command. It goes straight to a page with a long list of codes the after a while, it goes right back to the same page I described above.
Please help me. I use this for my business and have orders I must complete right away.
