3. Double click on Scripter.exe to launch Scripter.
4. Press Ctrl+A to select all of the existing lines then press DELETE.
5. If you copied this script, press Ctrl+V to paste it into Scripter. If you downloaded it, click File | Open, select the BAS file from your downloads directory, and click Open.
