I have always used the CLS - a2cmd.exe as listed here:
http://www.emsisoft.com/en/software/cmd/
I would always retrieve a new copy via:
http://download1.emsisoft.com/a2cmd.zip
Since Sept 19, this file appears to be old and not updated. Why?
Also on the page above, near the bottom there is a Download section with a link that points to:
http://www.emsisoft.com/en/software/download/
but there no longer appears the CLS to download on its own. That page should be updated to inform the user
that CLS is no longer available as a separate download and perhaps refer the user to:
