I had the same problem but with chrome looking at the code of the page I found the link of my download
if you want maya 2013 64bits english for windows here is the link
I also have this problem and I... kinda found way to get trough this. When you open the page where the download link doesn't actually appear, you do the following:
After opening the page, get you mouse ready right over the plane where the link should appear;
Then press F5 and right after that, keep clicking in the place where the link should be;
The link actually is there for like a second after the rest of the page is reloaded(then it disappears), so you can manage to click if you're fast enough!
It worked for me
