Nothing works, tells me not active account and I can not play.
We're sorry for this small problem, you should have your browser info refreshed automatically after yesterday's update, but seems that something went wrong and a lot of users are facing this problem.
There's an easy fix for this:
Just refresh your browser info by pressing CTRL+F5, and if it's not enough,
Clear all your cache/temporary Internet Files (manually or using a software like CCleaner)
