I initially installed the Microsoft Visual Studio Express 2013 for Web on my desktop. My desktop runs Windows 8.1 with internet explorer 11. It ran fine until the license expire
I had exactly the same problem, here is what I did:
a) Go in IE, click on settings wheel then Internet Options and Security tab.
b) Click on Custom level button (make sure you select Internet zone).
c) In Security Settings window, under Scripting I set Enabled for Active scripting.
After that Sign In should work. Even though Chrome is default browser, it seems that VS uses IE for sign in process.
Hope this helps!
