Hm, I'm not sure what you mean about it not working on my site.
WPT says there are no 404's and the preview on that page is looking alright. I do see what you mean about the zip errors though and it's been reuploaded. Mind sharing these security firewall scans?
Also I would suggest that you look into getting a different firewall, I just scanned it with virustotal and nothing out of the ordinary popped up.
