Check that you have the files s_utils.psc in the same folder with the script.
If you use Windows Vista (Windows 7) - be sure that you have the full Administrator rights on this computer. You may test it just trying to log in the computer with the user ADMINISTRATOR - and run the script.
In case you have the Windows Vista (or Windows 7) - try to set the RSS.exe to run in WindowsXP SP2 - mode, and set the theme to classic.

Be sure that both files (s_utils and your script) have the extension *.psc.
The files must NOT have the extension *.txt or some other.
Only extension *.psc.
