Cannot copy files from WindowsXP PC to remote UNIX server

I installed and started WinSCP 3.0, and have connected to my remote server successfully. My problem is when I try to copy a file from my PC to the server (Ensim control panel). I have scanned the forum for help, but I am lost as to what I need to do. I am a novice in dealing with most of these things, so please explain in detail. Attached is the log of the error:

You server does not have scp1 binary or it is not in path. Try to select SFTP protocol on login dialog.
