All my uploads are failing. I can get to the ftp via other programs (filezilla, etc..). When I click the Test button I get this:
[DSt-2:1103#12] Failed to upload "C:\windows\TEMP\SqlBakTestFile.back" file.> Could not determine file size (550).
Could you please try to upload a backup file to that folder via Rebex FTP Test Client https://www.dropbox.com/s/rsnf5o0y4uhyld5/RebexFtpClient.zip?dl=0
