Upload confirmed, but didn't upload

I am trying to upload a normal files... under normal conditions and it doesnt work.

The file is a SWF file. I go to my directory (/public_html/video) and drag the file from my desktop to SmartFTP. The file is around 23mb. The file seems to upload in like 1 second...and im on a standar Cable connection. I then try to view the file online and it is the same file as and older version. I also tried to upload it using internet explorer and i didn't get an error but internet explorer uploaded it instantly as well.


Whats wrong?

I am having the same problem as this poster form this form: http://www.techspot.com/vb/all/windows/ ... -swfs.html

Just noticed that other files will upload just fine. For some reason the swf file wont.
