Earlier today, I installed DVD Shrink, no problem.  Later in the day, I go to switch users, and I find out it's disabled.  "Ok" I think to myself, so I go to the logon settings, and try to enable it.  It refuses to stay enabled.  I go system services and try to enable Terminal services and Fast user switching, but they won't start.  Whether they're set on manual or automatic.  I'm a bit frustrated now, so I go to uninstall DVD Shrink, thinking it may be the source of my troubles.  Wrong.  Nothing changes.  I have no freakin idea what I did, or why it won't enable.  Any ideas?
