Administrator user is not the Administrator

Hi!

I did some stupid stuff. Somehow I set the Administrator as a Debugger
- and my User as the administrator.

I tried to revert that back and in the process I have erased my user.
The only user left is now the Administrator. However, it is not the
real Administrator. The real administrator user is somehow hidden... I
can't log into it.

When I load the Safe Mode - I have an empty screen - with only the
"Turn off the Computer" button. If I click CTRL+ALT+DEL - I can enter
the administrator user - but it is that stupid limited administrator
account - and still no access to many of the Windows configuration
screens.

Can it be that I have no Administrator account? I don't see it in the
"Administrative Tools" screen...

Thanks For the Help!
