same thing happened to me i fixed it by clearing my cache then restarting my computer. ONe thing that you could check to see if you can just use internet explorer instead of firefox. i was on http://freenapkin.com when i told myh flash player was outdated and I would not be able to view any of the FAQ help videos if i didnt update. I tried in firefox then i tried in explorer and was able to download it. I thiknk this is because firefox downloads can sometimes be prone to malfucntion so try IE make sure you have the latest version of IE though.
