After logging in, just a blank page

After logging in, just a blank page

First, I'm unsure what version I'm using.  I know it's 10 - but I don't know the exact version #.

The problem I have:  After I log in, the webpage is just blank and leaves me at the URL:   http://localhost:8020/upgradeLicense.do?actionToCall=loadDetails&showInline=true

Not much I can do here.  Just a blank page.  I've logged in using IE, Chrome, Firefox.  Cleared my cache.  Even downloaded Opera and tried that.  Nothing but a big blank page.

Any suggestions on what I can do here, aside from uninstalling/re-installing?

Thanks in advance for your reply.
