Sorry for the answer, but you will need to reinstall. Wow, I think you are magic if you somehow deleted the "Administrator" profile... It should be unremovable. It holds the key system info, every other profile is a sub-profile of adminstrator. I think you just renamed it and confused your adminstrative properties... I don't think it is possible to delete all administrators since there always must be at least one "superuser". There is always the default account named "Administrator" you should have created a password for it when you installed windows.
