When I press the [Game Start] button, nothing happens.

Same issue, Today i cant log on, cause the game start problem didn't work, I already send the ticket and please fix that problem, hope to fix it today, Thanks for you response.

 

Check your Windows Firewall/Defender quarantine folder aswell,
win defender might moved files into it.

 

Its working Thank you
