3.42 installing over 2.00

Version 2.0 was working fine.
I recently lost the owner settings of all programs, so I downloaded 3.42.
When starting
> selecting a session which is still stored
I see Network Error, Connection refused.
Other aplication (Putty, WS_FTP) are connecting to my Suse 8 server with SSL.
Even the old WinSCP 2.0
The ISP has set toSSL 2 only.

Is there a log?
Do I have to uninstall the Version2?
What do you recommend as settings?
Thanks a lot, Pedro

I suppose that you've meant SSH, not SSL. Neither Putty nor WinSCP is SSL client. Can you try to connect with the latest version of Putty (development snapshot).
