Host "C" does not exist - trying to synch FTP

This script gives me Host "C" Does not exist error.
I simply want to download all the folders from FTP over to the local machine.

It doesn't even matter what .txt file I drop onto the .exe. I can drop a .txt file containing nothing or exit. The result is always that the app opens up and the "searching for host" popup comes up.

You cannot drop a script file on WinSCP.
