R7000 Firmware and display issues

I installed a new R700 a few days back.  When I was settting it up, It told me there was an upgrade available.  I did the upgrade.  Now, when I log in, it just brings up blank pages.  Literally a white page is shown.  No text, no links, no nothing.  Now I believe that the pages are still there but I am not able to see them.  I say this because if I move my mouse areound the screen as it passes over hyperlinks the cursor changes.  But I cannot do anything because I cannot see anything.  If I click on one of the invisible links, it just brings up another blank page.

 

Obviously this is not a good situation because I cannot finish setting up the router. 

 

I was thinking, maybe , the upgrade needs to be run again?  But I cannot do that because I cannot see the links to click.

 

Any ideas on How to get the firmware gui visible again?
