I've just had the problem that when I clicked LOGIN, I saw a webpage inside Intel XDK, and when I typed in my username and password, I got ERROR 500.
But it works now.
EDIT: it doesn't work again.
Here's an error message I got:
[quote:3hf7aecm]The login and authentication system is experiencing problems. It is unclear, at this time, how long it will take to resolve this issue. Please have patience while this issue is being investigated.
