Classic FTP mentions Editing file - but does it have a Catalina Version?

Does anybody know if the lastest paid-for version of ClassicFTP works on Catalina?

I know FTP is old technology, but I have an old archived website of nothing but personal interest and KOMPOZER no longer works on Catalina to edit dead link. I notice that last year's paid for version of ClassicFTP mentions editing: "From NCH Software:Classic FTP Plus for Mac is an easy to use ftp client to view, manage, edit, upload, download and delete files from a remote server or network. " But I can't see any information or contact to ask if they have updated it to work on Catalina. I had the previous free non-editin version of FTP but it stopped working with Catalina of course..
