It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

Have you tried running it through your desktop shortcut?
Try setting "Run as admin" in the game shortcut properties and launching it from that.
Try setting compatibility modes (XP for example) in the shortcut. If that doesn't work then send a ticket to our Support people, maybe they'll be able to help you out.

Choose "technical issues with games" and Support should take a look at your problem.
