I had this problem and this fixed it for me:
"Something to try:
If you are getting the NetSSLError:
If you are running Microsoft Windows 7 x64 version 6.1 (build 7600) [you can check your version by searching winver and running the exe]
go to the following link:
http://www.microsoft.com/en-us/download/details.aspx?id=5842
Download the second to last update (windows6.1-KB976932-X64.exe, should be ~900mb)
Run it. Couple of my friends have had success fixing the NetSSLError issue this way."
