Error "the parameter is incorrect" in NIS 2009

I have used NIS 2009 without incident for a month or so on a windows xp machine.  I noticed that after a reboot today, it didn’t load automatically.  When I attempted to load manually, I got a message “the parameter is incorrect.”  I attempted to uninstall and got the same message.  I attempted to reinstall and got the same message.  I attempted to run the norton removal tool and got the same message again.  I’ve reviewed a couple of other threads that mentioned a similar problem, but none of the suggested solutions works for me.  Any ideas?
