authentication failed, enter password

version 3.7.6 tries to connect and asks for the password. Type it in and continues to cycle asking for the password.

I installed version 4.3.9 and received the same results:

On one machine (windows XP) it works properly with version 3.7.6. On a windows 7 Ultimate computer it cycles asking fof the password. It had been working properly on this computer until today.



Below is the log file from the attempt on the windows 7 uplimate computer: Thanks in advance, on any help on how to proceed.

Last evening, I used the WinSCP to send my claims to nc medicaid. However, I was showing someone else how to use it for when I go on vacation this morning and it will not let me on. It keeps denying my password and access is denied. I have since downloaded the newest version and am still getting the same denial. Is there something that has changed or is something wrong with the WinSCP?
