What doesn't make sense is that when my colleague tries to download the files, he gets the same error that i am having. When he deletes the file that i have transferred over and uses WinSCP on HIS machine to transfer the same files over, he is able to download it successfully. We are almost certain it is something to do with my WinSCP.
I have tried using SFTP, SCP and FTP. I have also tried transferring them from my local drive and shared drive. I have also uninstalled and reinstalled the newest version 5.13. I am running Windows 7 Enterprise.
