Help! I screwed up my sons laptop

Yesterday my wife and I confiscated our sons laptop due to poor
grades. While we had it we decided to create an administrator account
and to implement parental controls. The way we did this was to change
his account from administrator to standard user and change the current
generic account that was there to an administrator account. We password
protected it and set our parental controls. The problem we face now is
when the computer is turned on only one account is displayed as an
option. This account is our sons and as mentioned it was changed to a
standard user. The admin account is within his account. He tried to
access something and it prompted him for permission. When my wife and I
entered our password it will not accept it. Correction, it doesnt say it
is the wrong password it says "Logon Failure, the user has not been
granted the requested logon type at this computer"... I tried to go to
the control panel and this computer will not let me access anything
administrator related. Every time it prompts for a password it gives me
the same "logon failure" comment. I wanted to restore it back to another
restore point but he has never set it up to create restore points. I
asked him if he got any discs with it but again, he has no discs for the
computer. Is this just an issue of me finding the right door or screen
to enter my admin password? Where do I go to fix this? As it stands I
have an admin account set up WITHIN a standard user account. I'd like to
start over and separate the two. PLEASE HELP!! I have gone from
responsible parent to the biggest A-hole in the world to my son.
