Question : Your SQL Server installation is either corrupt or has been tampered with (unknown package id).  Please uninstall then re-run

I got this message when booting up.  Now, I cannot use SQL Server at all.  I get the same message when I try to connect to the server.  The only recent change has been the installation of MSDE 2000.  I cannot uninstall that (fatal error during installation message).  Please help!  I have this same problem on another machine and tried uninstalling and reinstalling SQL server and it doesn't do any good.  It seems to be related to MSDE.
