Can you post a log file from Filezilla SFTP session?

Hello. I seem to be having a very similar problem as another user. I am trying to connect WinSCP to WS_FTP using SFTP. I have no issues connecting with FTP or if I use Filezilla I can connect using both SFTP and FTP. Here is the log file for WinSCP. I realize it must be a simple setting that I am missing but I am not sure what it is. Please help!
