i just reinstalled the game after encountering this problem apon my first installation.
that is the code i'm provided.
the game never opens after clicking play, it says the game is running on battle.net for a moment then i get the error message.
Please Help me
I'd suggest that you open an official support ticket with Blizzard through their website. They'd be far more capable of helping you through this issue.
In fact, someone else had a similar issue. https://us.battle.net/forums/en/d3/topic/16283269114
Perhaps that will be of some use to you. Best of luck!
