Ftp.dll is for FTP and FTPS (FTP over TLS/SSL) protocols.

FTP runs on port 21, FTPS on 990. Use Connect(string host) and ConnectSSL(string host) to conenct to default ports.

No joy!  Now it fails to connect before it even gets the Login information.

As I said Ftp.dll is for FTP and FTPS - SFTP is completely different protocol

In searching your site, I found an answer...  Limilabs does not support SFTP and has no plans for it in the future.  This makes this dll useless for us.  It was a bad decision to purchase.

It's a _different_ protocol, they have absolutely nothing in common!

Your purchase was over a year ago!

That is true...  It obviously still was a bad decision.

Ask your server administrator, maybe this server supports FTP/FTPS as well, and it only needs to be turned on.
