Here's the link to their download page <edit: link broken; just follow guide>
I got this by going on the "Order now" page and viewing the page source, I did "CTRL+F" and searched for the word "return" until it took me to a place in the source which said
Code:
name="return" value="
I then copied and pasted the URL which followed the "value=" box (which is the url in the first paragraph). This tricks the site into thinking you've paid and allows you to download. Enjoy.
edit: well the link doesn't work anymore, just follow my guide on how to get it. Any questions post here.
