      After receiving an "unknown publisher" message on my Photoshop Elements 9 program, I uninstalled it and reinstalled it.  The reinstallation froze on the update screen.  The program would not reinstall.  I have the serial number and am using Windows XP.  Elements 4 has also been installed on this computer, but will not function now.  Please advise.
