Got prompted to update to 5.2.1 & installed update. Rebooted & update continued along with a update to WinPcap. Had trouble with the URL Sniffer so I rebooted again.

Now, trying to download from multiple sites, I get the following error "HTTP/1.1 400 Bad Request" immediately upon trying to DL.

Seems to be a problem with this update or the new WinPcap? Or maybe a firewall issue?
