Error message from Download Tool

[Arek]

Hi,

Download Tool works correctly - the files pass through it and successfully arrive to destination (put to ftp server).

However such error message comes from Download Tool: "Error transferring data: Upload failed (at start/before it took off)".

How can I get rid of it? Thanks in advance for any suggestions.

Fixed. It was a mistake in configuration, the same file was sent multiple times. First time always pass ok but the next attempts at sending the same file randomly caused an error.
