Thanks - I found the customError and changed it from
<customErrors mode="RemoteOnly" defaultRedirect="~/error404.aspx">
<error statusCode="404" redirect="~/error404.aspx"/>
It seems when I re-ran that SQL query that it re-created the admin account, so there is two of them now. I was able to delete the information via the DB, changed the web.config file again and upload that. That worked.
