I just purchased the Advanced FTP (Optional Features ) Yesterday
But the License Manager still shows the Status of FTP Advanced is "Disable" Today,
Can the Advanced FTP been enabled automatically or need to do something manually to enable?
You need to download your new licence certificate and install it. The email after purchase should include all you need but, if not, go to https://www.gpsoft.com.au/DScripts/lostcode.asp and type in your email address and it will mail the new certificate to you.
Thank you, Leo, I had followed your steps to enable Advanced FTP
