My friends can play and I've not seen much with people having this issue, so I haven't seen any fixes for it. I just sent a ticket to the support.
same issue here.
This is due to some weird changes happened to Windows IE settings.
Open Internet Properties from start menu.
Go to Advanced
Scroll down and uncheck both:
"Check for Publisher's certificate revocation"
"Check for server certificate revocation"
reboot computer.
