You need a copy of KeyLock which is on MS ERD Cd

I guess you don't have it. But yes, as stated. Do a reinstall (over the top) of what you have so that you don't lose much and reset the Administrator PW then.

Also, always have a 2nd account that has full Administrative rights. You would be all set now if you had one

SHould have been Locksmith and not Keylock

This. I second the vote for keylock. I had to do the same myself. Keylock will override the changes you made.
