Maybe I misunderstood the question. However when I visit the download.com web page I have no problems opening the link. However, if you're using Firefox or another tabbed browsing browser, if you attempt to open this link in a tab it will not work because it's using JavaScript to open the link.
If you're trying to create a link on a separate page by using this source code it's likely not working because there is another portion of the JavaScript code elsewhere in the code that is needed for the link to work.
p.s. I added the code link to your message so it didn't scroll all the way to the right.
