FTPS Connection Does Nothing

I have created an FTPS connection to my IIS-based FTPS server, imported the cert, etc. but when I try to connect, SmartFTP looks like it's trying to connect in the server tab and the [Initial Folder] drop down, but that's it.  The connection log is empty except for:
 
[<TIMESTAMP>] SmartFTP 6.0.2157.0
 
I have placed Wireshark on the box and there is no traffic attempting to reach the FTPS server, nothing.  If I try to connect using the old Windows Command Line Client, I can connect but get kicked after logging in since that client doesn't support FTPS.  That is expected behavior and I can see the traffic on Wireshark.
 
This is happening on two different clients, both Windows Server 2008 R2.  I have successfully connected using the same version of SmartFTP from my Windows 7 laptop.
 
Any suggestions would be greatly appreciated.

Install the latest version and try again:

Updating didn't fix the problem, but it at least allowed SmartFTP to start logging and showed me what the problem was.
 
 
 
Issue is resolved, thanks.
