The best you could hope for is a bulk download of the latest versions of all programs you downloaded earlier, not a bulk install. But then you would also get the programs that you once installed and deleted later.
But I'm afraid that this option isn't present at all and you have to download each one of those programs yourself from your browser.
Be sure to set the preferences in your profile to "don't use the cnet-installer". And be aware that more and more proigrams install more and more toolbars and other things you don't want, sometimes even if you uncheck every such option from the installer screen.
If yoiu keep a backup of everything you downloaded, that might be helpful next time.

I have had my account forever and was hoping instead of finding all of my favorite downloads one by one i would be able to do a bulk inatall.
