Can't install indesign

I have Adobe Web Premium CS4 and use it happily.  However, I now need InDesign. I have been using Microsoft Publisher, but I'd like to try InDesign as I think it would function better. The single app options looks like it suit me perfectly. But, I can not get it to install.  I can open Adobe.com and log it.  I can click on my membership where it shows I had a trial period of Creative Cloud Free Membership. That is all that is listed.  I try to click "manage plan" and get a blank page.  I try to go through the indesign page at Desktop publishing software | Download free Adobe InDesign CC trial, This page loads but then when I click on free trial (https://creative.adobe.com/products/download/indesign?promoid=KSPFR) I get nothing but blank page.  I try to click buy now since I think I will like it enough to purchase (Creative Cloud pricing and membership plans | Adobe Creative Cloud) and get nothing but a blank page.  There is no pop-up blocker enabled.  I completely TURNED OFF my antivirus (Norton) to be sure there was no conflict there.  Everything else on the computer is running fine including the internet.

I have managed (with some difficulty) in getting the Trial Version of InDesign on my secondary computer (Windows Surface Pro 8.1) and it appears to be running. However, I would like to be sure I can also use it on my other computer!  Thoughts??

My computer is running Windows 7.

Internet Explorer 11.  (most up to date).
