We're sorry to hear you're facing this problem. It's caused by today's new release of our plug-in and the resultant overwhelmingly high demand. Unfortunately, this is causing part of our website and online services (affecting mainly downloads) to be affected. Our engineering team is dealing with those issues we hope to get it back to normal soon and we'll keep monitoring the traffic. It might be worth trying later once demand has subsided.
On behalf of the whole team, I'd like to express our sincere apologies and we are more than happy to answer any questions or concerns you have.
