I'm using the latest version of Opus (12.8 x64 build 6688 4/24/2018) at least according to the updater. When I try to connect to some FTP sites it works just fine, but when I try to connect to sites that use "Secure TLS Explicit (AUTH TS)" as an option, I get the following error dialog: "Error Initialising SSL. Error: Libeay32.dll Not Found failure. (126)". Help?!
You know what? You can close this topic. I discovered the auto-updater wasn't going off anymore. Manual attempts to run it just didn't do anything. I think my install was corrupt. I manually downloaded the latest version from the web site (12.9) and it solves my problem. Sorry for the trouble!
