Unable to Sign In to Visual Studio 2013

Question

I recently installed Visual Studio Ultimate 2013, and when I tried to Sign In to my Microsoft Account, I get the following error:

SP324099: Could not

Answer 1

I can't sign in in Visual Studio 2013 community. Something broken. VS2013 welcome sign in page didn't work. The solve was to try download VS2015 from official site

I got error when click download VS2015: I should join Dev community or purchase. I click "join" - download page was loaded. VS2013 login page starts to work on my PC.
