The setting that is keeping you from downloading is not controlled by the Air Live WLAN USB :-(
Somewhere on your network there is a piece of software that's called an ISA firewall and this is keeping you from downloading. There is a special filter in place to protect the network from downloading executables from the Internet. It is called an HTTP filter and can be set to less restriction. In your case (considering the error you get) this ISA fireall needs a patch. So you must get in contact with the guy controlling this ISA firewall on a Windows Server which is connected to the Internet.
Hope this helps.
Richard.
You will not be able to bypass ISA server very easily. You need this ISA to connect through the Internet. Further it sounds to me that you guys have something to talk about if he's the only one around that can help you out :-(
Talk to the guy, you can explain him what you need. Maybe you can let him download it for you. Isn't there anything you can get him to do for you? e.g. pay him more or let him loosen up :-)
