Failing to download

Whilst I understand that this may not be the correct platform for my question, but in my frustration, I thought could just use this plat form.

I just joined techrepublic today, and was very excited to see all those downloads, and in my excitement I scrolled down the downloads, in the process noting down the numbers. Only to be disappointed when I failed to download more than 10 deiffrent ones. Could there be a problem with the downloads?
