WIN 7 install will not take password XP install does

WINSCP 5.5.5 installed on Win 7 pc but same password used for same site setup on XP 5.5.1 install gives me 'Access Denied' on Win 7 pc. Need to get off XP pc but WINSCP will not allow access to 2 sites although other common sites do work. See log attached. What does 'Sending Special Code 12' mean?

What version of WinSCP were you using on Windows XP?
Try 5.6.5 RC and enable Log passwords and other sensitive information.
Check the log to see what password is WinSCP trying to use. Please, let us know what you find.
