This is why I hate these posts so much. They blame the wrong things, provide wrong information, and haven't read the rules about what information is helpful. I have no idea even what LW version is being used here. Sheesh.

Oh well, help has been asked, but I can only reinforce what you've already suggested LOTR.

No incoming connections are because there is a block in the network, probably because many schools block upstream somewhere.

So, who controls that? Ask your school's network admin why you can't download. It's a networking problem. Actually, I'm surprised LW even managed to connect to others to allow search results to get back to the machines. Does the admin tells you there are no restrictions on downloads?

For a reliable test, get the admin to try any of the free and legitimate files from http://magnetmix.com/video.shtml

If the video of "The Scene" won't download, try the "more info" link and find the web download link as a comparison.

Let us know what you find (version and other info, admin's answer, magnetmix comparison results).
