Help - Issue Uploading files

Hi Guys,

I wonder if anyone can help, I am new to using the programme. I am looking to upload some pictures of Le Mans to an FTP site, I am connected to the server, however I keep on getting the following error message:

[15:19:58] 550 P1010604.JPG: The system cannot find the file specified.

I have moved the files from my pictures to other locations on my C Drive, this makes no difference.

Sorry for the stupid question, Kind of feel like Forrest Gump ;-)
