Transfering swf files via FTP

Im using Smart ftp and trying to transfer a swf file over to my awardspace folder to test how it runs on the internet.
At the moment I cant transfer any new swf files, all my old ones (which are only about 2 weeks old) still seem to transfer over fine. When I try to transfer a new swf (hunter.swf) it says the transfer failed.
I get the following message on my log

Ive had no luck in solving my problem on other forums, does anyone know why the transfer might be failing? Because all files other then these new swf files seem to work.
