I assume some of you had this problem with the game.
I will write a guide on how I fixed the problem, hope it helps you too.
First of all, go to Control Panel >> Network and Internet >> Network Connections.
Then click on your main adapter and then properties, just like the picture.
Then select, Internet Protocol Version 4(TCP/IPv4) and click properties
Then select Use the following DNS server addresses, instead of obtain a DNS server automatically
And put the following addresses just like the picture:
208.67.222.222
208.67.220.220
Hope it helps you all!
