Having a hard time downloading any of the programs from the website

Hi!

I've been trying to download the following applications:

Mozilla Firefox Portable
Mozilla Sunbird
FileZilla Portable

but I can't seem to download any of them. Whenever I click the "Download Now" button, I am lead to the page that says something like, 'Your download will start shortly'. Afterwards, I am redirected to this site: http://sourceforge.net/projects/portableapps/files/ As soon as I reach this page, my browser automatically hangs.

I also tried to click on the mirror and direct link to no avail. Last night, I downloaded Open Office, which worked just fine. I wonder what's wrong?
