Protection Center UI Stub has stopped working

I am running Windows VISTA with several users with NIS 2011 being used by all users.  Under one user ID I cleaned off some start-up programs.  Unknowingly, I removed NIS.  Now for that user, I get the Protection Center UI Stub... message.  For all other users, NIS is working fine.  How do I get NIS to work for the user who deleted it from the start-up menu?
