Windows 7 issues with logging on?

So, here's what I've been doing.

I have been creating an account with command prompt on the logon screen (I hacked my computer to open command prompt instead of sticky keys when you press shift 5 times), but now, for some reason, when I create he account from the logon screen, I cannot log into it. It gives me an error message "The User Profile Service failed the logon. User profile cannot be loaded"

This has not happened to me before, and I have created plenty accounts with command prompt on the logon screen in the past.

I do not have access to the other 2 accounts right now, so I don't know if this same thing is happening to them right now. (By no access I mean I don't know the password)

Does anyone know a solution, preferably something I can do with command prompt?
