I am going to assume that I am supposed to download this latest version from the Downloads area in my webassist.com account.
I am also going to assume that the idea here is that I delete all files and start from scratch to test the whole.
No harm done if I have misunderstood and the download file is in a different location, because I can always redownload. And I will of course simply rename the folder on my site and create a fresh empty folder, so I can always revert if necessary.
Thank you, off to do that now.
